Ofcom specification opens up 60GHz for wireless gigabit Ethernet

Frequency dependent attenuation of electromagn...Image via Wikipedia
In a move that has crept under the radar (!) the UK regulator Ofcom has opened up the 60GHz band for unlicensed operation.
It is to open the spectrum in the 59 – 64 GHz band for Fixed Wireless Systems (FWS) and to combine this with the existing 57 – 59 GHz band under one overall licence exempt authorisation approach for FWS. This creates one contiguous and flexible block of spectrum providing 6.8 GHz of available bandwidth (57.1 – 63.9 GHz) taking into account two 100 MHz guard bands.
The large bandwidth available makes the new 57.1 – 63.9 GHz band (the “60 GHz band”) suitable for very high capacity, short hop FWS (e.g. 100MBit/s ~ 1GBit/s Ethernet systems). In addition the technical conditions that will be implemented along with the high propagation attenuation around 60 GHz will allow sharing between a wide range of applications (e.g. FWS, ITS, Wireless HD and others).
The various technical characteristics of the systems to be deployed, along with the high gaseous absorption propagation attenuation around 60GHz (see chart) implies that sharing should be possible between the various applications (Fixed, ITS, wireless HD & other) with a very low probability of interference.
Ofcom has also decided to incorporate a minimum antenna gain of 30 dBi into the technical conditions to
ensure that narrow beam antennas are employed. This decision will also bring the technical conditions into line with the new ECC recommendation ECC/REC/ (09)01 that replaces ERC/REC/12-09.

The publication of the Final Regulatory Statement on licence exemption and exemption regulations come into force in the summer of 2010.

Elpida Begins Mass Production of 40nm 2Gbit DDR3 SDRAM

DIMM with eight DDR3 SDRAM devices.Image via Wikipedia
Elpida Memory has started volume production of 40nm process 2GBIT DDR3 SDRAMs that will bring the price of DDR3 chips down and drive further adoption. Since completing development of the DDR3 SDRAM last October it has taken Elpida only two months to ramp up mass production at its Hiroshima plant.
The new 2Gbit device fits 44% more chips per wafer compared with Elpida's 50nm DDR3 SDRAM and a 100% yield for DDR3 products that operate at 1.6Gbps, the fastest speed standard for current DDR3. It also supports high-speed products. Compared with 50nm products, it uses about two-thirds less current and supports 1.2V/1.35V operation as well as DDR3 standard 1.5V, resulting in reduced power consumption of around 50%.
In the second quarter of 2010, 40nm process production will also begin at Rexchip, a subsidiary in Taiwan, to increase the manufacture of 40nm process products in order to lower products costs. Depending on conditions in the DRAM market, Elpida may transfer 40nm process technology to foundry partners ProMOS and Winbond to expand production based on this technology to an even higher level.

UK Companies Slow to Grasp Plastic Electronics

We are on the brink of a new age of Plastic Electronics, production costs are tumbling and business opportunities are growing exponentially, yet companies are slow to take up the innovation challenge, according to research from the Advanced Institute of Management Research (AIM Research).
"Yoghurt pots that flash at you to say they're mouldy, animated e-papers like Harry Potter's Daily Prophet, smart packaging on pills that beep your doctor when you forget to take them - these applications are no longer the stuff of sci-fi," says Dr Zella King of Henley Business School. "Today, Plastic Electronics can already offer huge growth opportunities for companies."
The Plastic Electronics industry is predicted to be worth $335 billion by 2029, and the UK is leading the way on global innovations. Networks of UK universities and companies are collaborating on new technologies and products. As a measure of its significance, the UK Government launched its PE strategy on December 7 this year.
The opportunities are vast. The technology is here, and Plastic Electronics products are already being manufactured on a commercial scale. What is lacking, however, is involvement by product designers and market-led end users. Companies in the retail, healthcare, transport, electronics and packaging industries have yet to understand the revolution taking place. "They need to realise this is no longer the domain of electronics companies," says Dr King, "it is open to anyone seeking to add value to their existing portfolio by using new technology."
Smart companies got in at the start. Esquire magazine wowed readers last year with the first animated e-paper magazine cover. In January, Plastic Logic will launch QUE, its shatterproof, wireless, A4 e-reader no heavier than Vogue. And the latest range of intelligent bandages can measure oxygen levels in a patient's wound to determine when they need changing. A tiny antenna, printed into the fabric, then beeps the patient's doctor.
The beauty of Plastic Electronics is that electronic materials can be formed into circuits using cheap core materials. Products can be printed onto flexible surfaces like paper, film or fabric allowing the manufacture of thin, lightweight devices that will not shatter like glass-based liquid crystal displays. The costs are so low that, for example, disposable interactive games can be made for consumer promotions, sensors can be incorporated into smart packaging and bandages, and clothing can be printed with wearable electronics and solar cells.
But innovation is moving fast, and there will only be a small window of opportunity for companies to gain competitive advantage and global market share. The research suggests that strong business models are needed to channel the UK's world-leading expertise into the development of Plastic Electronics components and businesses. This will only happen where collaboration between technology companies and research organisations is led by firms that have a vision of how to create customer value from Plastic Electronics.

Arizona State stacks nanoscale memory chips

Researchers improve chip memory by stacking cells

Researchers at Arizona State University have developed an elegant method for significantly improving the memory capacity of electronic chips.
The researchers have shown that they can build stackable memory based on 'ionic memory technology' which could make them ideal candidates for storage cells in high-density memory. Best of all, the new method uses well-known electronics materials.
“This opens the door to inexpensive, high-density data storage by ‘stacking’ memory layers on top one another inside a single chip,” said Michael Kozicki, an ASU electrical engineering professor and director of the Center for Applied Nanoionics. “This could lead to hard drive data storage capacity on a chip, which enables portable systems that are smaller, more rugged and able to go longer between battery charges.”
“This is a significant improvement on the technology we developed two years ago where we made a new type of memory that could replace Flash, using materials common to the semiconductor industry (copper-doped silicon dioxide). What we have done now is add some critical functionality to the memory cell merely by involving another common materia – silicon.”
Kozicki outlined the new memory device in a technical presentation he made in November at the 2009 International Electron Devices and Materials Symposia in Taiwan. Kozicki said that given current technology, electronics researchers are fast reaching the physical limits of device memory. This fact has spurred research into new types of memory that can store more information into less and less physical space. One way of doing this is to stack memory cells.
Kozicki said stacking memory cells has not been achieved before because the cells could not be isolated. Each memory cell has a storage element and an access device; the latter allowing you to read, write or erase each storage cell individually.
“Before, if you joined several memory cells together you wouldn’t be able to access one without accessing all of the others because they were all wired together,” Kozicki said. “What we did was put in an access, or isolation device, that electrically splits all of them into individual cells.”
Up until now, people built these access elements into the silicon substrate.
“But if you do that for one layer of memory and then you build another layer, where will you put the access device,” Kozicki asked. “You already used up the silicon on the first layer and it’s a single crystal, it is very difficult to have multiple layers of single crystal material.”
The new approach does use silicon, but not single crystal silicon, which can be deposited in layers as part of the three-dimensional memory fabrication process. Kozicki said his team was wrestling with how to find a way to build a diode into the memory cell. The diode would isolate the cells.
Kozicki said this idea usually involves several additional layers and processing steps when making the circuit, but his team found an elegant way of achieving diode capability by substituting one known material for another, in this case replacing a layer of metal with doped silicon.
“We can actually use a number of different types of silicon that can be layered,” he said. “We get away from using the substrate altogether for controlling the memory cells and put these access devices in the layers of memory above the silicon substrate.”
“Rather than having one transistor in the substrate controlling each memory cell, we have a memory cell with a built-in diode (access device) and since it is built into the cell, it will allow us to put in as many layers as we can squeeze in there,” Kozicki said. “We’ve shown that by replacing the bottom electrode with silicon it is feasible to go any number of layers above it.
With each layer applied, memory capacity significantly expands.
“Stackable memory is thought to be the only way of reaching the densities necessary for the type of solid state memory that can compete with hard drives on cost as well as information storage capacity,” Kozicki said. “If you had eight layers of memory in a single chip, this would give you almost eight times the density without increasing the area.”

MPEGIF Launches “3D over MPEG” Campaign

The MPEG Industry Forum (MPEGIF) has formed a 3DTV Working Group with a “3D over MPEG” campaign. The new working group and campaign continue MPEGIF’s successful work in furthering the widespread adoption and deployment of MPEG-related standards including MPEG-4 AVC/H.264 video compression technology.
“3DTV is of keen interest to everyone in the video creation and delivery industries. The challenge we all face is that of sorting through the myriad technical options. Our common goal is to create a 3DTV ecosystem that delivers great new experiences to consumers.” says Dr. Sean McCarthy, chair of the newly formed 3DTV Working Group and Fellow of the Technical Staff at Motorola. “The 3DTV Working Group and the ‘3D over MPEG’ campaign are designed to provide focus and clear information to decision makers. 3DTV can be distributed today using MPEG-related standards. Existing broadband and broadcast services and infrastructures are 3D-ready, and ongoing works by standards bodies provide a compelling path for the future evolution of 3DTV.”

The 3DTV Working Group will provide a forum for free exchange of information related to this emerging technology, an industry voice advocating the adoption of standards and for consolidating the overall direction of the 3DTV industry. Its focus and constituency will be derived from video service providers, consumer electronics manufacturers, content owners, equipment manufacturers, system integrators, software providers, as well as industry advocacy groups, industry analysts, financial institutions and academic institutes.
“3D video is showing distinct commercial promise in theatrical releases and could thus transition to the advanced living room to follow High Definition and Surround Sound. As a result there is a growing array of competing technologies and work from various standards bodies”, said David Price, Vice President, MPEGIF and Vice President at video compression company Harmonic. “It has therefore become a major theme of the next MPEG Industry Forum Master Class being held at CES 2010 in Las Vegas in January featuring leading executives from HBO, AT&T, Microsoft and other industry luminaries”.

New Driver for SuperSpeed Connectivity for SCSI Hard Drives With Advanced Features

Western Digital and NEC Electronics are collaborating to promote the new SuperSpeed Universal Serial Bus (USB) 3.0 standard in storage devices supporting data transfer rates of up to 5 gigabits per second (Gbps), 10 times faster than the previous high-speed USB 2.0 transfer speeds.
The companies plan to develop a USB Attached SCSI Protocol (UASP) driver to deliver hard drives with very high performance, mass-storage capacity. UASP is a new industry-standard, high-performance mass-storage protocol being developed for SuperSpeed USB 3.0 to overcome the performance boundaries of the Bulk Only Transfer (BOT) protocol, which has been used for traditional USB 2.0 speeds. The new UASP driver will be used with NEC Electronics’ USB 3.0 xHCI (eXtensible Host Controller Interface) host controller (part number µPD720200), which appeared on the market as the world’s first USB 3.0 host controller in June 2009.
Key features of the new UASP driver
(1) Support for the UASP mass-storage protocol
(2) Data transfer rate is enhanced by 30 percent, with optimized power efficiency and smooth interoperability, compared to the existing BOT protocol
(3) NEC Electronics’ license program is available for any LSI (large scale integration) vendors who develop UASP-based LSI devices

“The wide adoption of external storage, for both expanding and backing up internal computer storage, highlights the need for faster interface transfer rates. The USB 3.0 interface offers a significant advance in data transfer speed,” said Robert Caddy, Jr., vice president of engineering for WD’s Branded Products Group. “We are pleased to collaborate with NEC Electronics as a leading supplier of USB host devices in the introduction of USB 3.0 technology to the storage market.”

Farewell Zilog

Zilog, the inventor of the ubiquitous Z80 microcontroller, has finally given up the ghost and is to be sold to IXYS, a power semiconductor and mixed signal vendor that is one of the fastest growing semiconductor companies. The $62m deal is expected to be completed by March next year as IXYS expects the microcontroller market to take off again next year.
The combination of the two companies with complementing technologies will allow IXYS and Zilog to leverage analogue power management with digital control. Zilog has a focused MCU business with technologies that will complement IXYS’ product portfolio. IXYS has a broad based and diversified range of products geared toward industrial, telecommunications, medical, automotive, alternative energy and consumer applications. By introducing MCUs that enable digital power management and embedded control, IXYS will be able to create more cost-effective system integration solutions for its diversified customer base.
“As the world migrates toward SoCs, Zilog’s core microcontroller technology along with IXYS’ core power solutions create entirely new products that will meet the needs for today and tomorrow,” said Dr. Federico Faggin, Chairman of the Board and the co-founder of Zilog, Inc.

“We are pleased with this strategic acquisition that will allow us to penetrate more applications in traditional and developing markets, leveraging both of our strengths. Digital power management is one of the fastest growing applications in the markets we serve. Zilog’s 35-year history in microcontrollers with its legendary Z80 and Z8 architectures parallels IXYS’ pioneering technologies in power MOSFETs, IGBTs and HVICs,” said Dr. Nathan Zommer, CEO and Founder of IXYS Corporation. “With the expected rebound in MCU sales in 2010, we anticipate a growth in opportunities for refined power control in many applications; the acquisition and integration of this MCU business will strengthen our position and allow us to take advantage of these opportunities. We believe this transaction will create further value for our shareholders, employees and customers through a further expansion and diversification of our product offerings. As it is one of the pioneers of MCUs in Silicon Valley, we plan to keep the Zilog entity with its recognized and valued trademark.”
“Zilog has actively explored a broad range of strategic alternatives to enhance shareholder value. The price that IXYS is proposing to pay is a premium to our current stock price, as well as a substantial premium to the average of the prices at which we’ve traded throughout 2009,” said Darin Billerbeck, Zilog’s president and chief executive officer. “This acquisition brings liquidity to our shareholders, while increasing our financial stability in these continuing uncertain economic times.”

IXYS expects to increase its penetration in the automotive electronic and electric market by producing cost-effective integrated product offerings, including the power semiconductors, driver ICs and Zilog MCUs that are essential for automotive controls and driving displays. In IXYS’ prime industrial market, IXYS plans to deploy MCUs that are suited for motor control, power control and automation. In the telecommunications and security industries, Zilog’s MCUs complement IXYS’ ICs, which can be deployed in modems, VOIP, FIOS and automated alarm systems. For the medical market, the Zilog MCU platform complements IXYS’ power and IC products in defibrillators, imaging and diagnostics. Additionally, the recently expanded IXYS products for LED lighting and display, which require digital power control, will benefit in the market from the availability of complementary MCUs. MCU product offerings will be expanded to include low-power and sensing technologies for energy management applications, including smart lighting and intrusion detection.
In addition to expanding market opportunities, the acquisition will allow IXYS and Zilog to pool R&D resources, leverage economies of scale, reduce manufacturing costs and streamline and integrate operational and support costs.

The deal with IXYS will be through Zanzibar Acquisition, a wholly-owned subsidiary of IXYS.

The move ends a selloff of Zilog technology. In February Zilog sold key lines to Maxim and UEI for $31m. Maxim bought Zilog's secure transaction product line that includes the Zatara 32bit, ARM-based microcontroller family for use in payment terminals.
Maxim and UEI jointly purchased the wireless control business, with Mxim taking the microcontroller silicon chip business and supporting intellectual property to combine with its own Infrared (IR) microcontroller family. UEI bought the software portion of Zilog's wireless control product line, which consists of its patents, universal remote database and software, and related assets.

Single chip for HD image acquisition

HD image signal processors combine image signal conditioning circuitry, a 14-bit ADC, and precision timing core for medical, industrial and scientific designs

As medical, industrial and scientific markets increasingly adopt high-definition (HD) image acquisition systems, designers of such systems must confront a host of signal-processing complexities in order to accurately capture and record high-resolution images. Analog Devices (ADI) has developed two high-performance, highly integrated 14-bit HD image signal processors: the 75 MSPS dual-channel AD9978A--the industry’s fastest-- and the 72 MSPS quad-channel ADDI7004. These single-chip solutions enable designers to create multi-channel CCD (charge-coupled device) or CMOS (complementary metal-oxide semiconductor) HD image acquisition systems that can deliver the degree of clarity, visibility and accuracy needed for today’s high-resolution requirements.
Many leading manufacturers of digital still cameras, camcorders, scanners and other imaging systems depend on Analog Devices to deliver the highest performance products with the lowest power dissipation available. Analog Devices’ 75 MSPS dual-channel AD9978A and 72 MSPS quad-channel ADDI7004 HD image signal processors enable the high-resolution, high-speed sampling of signals from advanced image sensors, while consuming very little power—280 mW (milliwatts) and 530 mW, respectively.
“Until today, high-performance imaging system designers were forced to use multiple high-power components to sample image signals at HD rates,” said Stuart Boyd, product line director, Digital Imaging Systems at Analog Devices. “By integrating high-performance signal conditioning circuitry, a 14-bit data converter, and a precision timing core into a single HD image acquisition solution, designers can achieve an unequalled combination of speed and accuracy in high-speed, high-resolution digital imaging systems, while eliminating the power dissipation limitations that restrict portability and increase design cost.”

Accurate and Sharp HD Images for High-speed Applications

The AD9978A and ADDI7004 devices extend Analog Devices’ family of AD997x image signal processors for high-speed digital imaging applications. Each channel integrates a complete AFE comprising a black-level clamp, a CDS (correlated double sampler), a 1bit VGA, and a 14bit ADC. Analog Devices’ Precision Timing core provides adjustments for the CDS and SHA (sample-and-hold amplifier) clocks with 210ps resolution at 75 MHz (ADD9978A) and 217 ps at 72 MHz (ADDI7004). The AD9978A and ADDI7004 also contain a reduced range LVDS (low-voltage differential signaling) interface for the image-data outputs to increase performance and reduce EMI issues.
The power consumption of each device is proportional to its sampling frequency. Both high-resolution image signal processors support designers’ efforts to standardize their image sensor interface designs across multiple platforms, eliminating the need to change or add additional components and reducing overall system cost across several models. Additionally, the AD9978A offers pin-for-pin compatibility with the industry-standard AD9978 14-bit CCD signal processor, enabling designers to easily change existing designs to deliver high-end performance.
The dual channel AD9978A costs $25.32 while the quad channel ADDI7004 costs $48.12.

First Cortex-M0 microcontroller starter kit

$139 starter kit for popular low cost microcontroller

IAR Systems has developed what it believes to be the world's first commercial starter kit for ARM Cortex-M0-based microcontrollers for the NXP LPC1114.
One of the features which enabled the speedy development of this kit was the fact that the NXP LPC11xx Cortex-M0 family is 100% pin compatible with the NXP LPC13xx Cortex-M3 family. "This kit is proof of that concept. We were able to re-use 100% of the design from our recently released LPC1343 kit," said Sara Skrtic, Development Kits Manager at IAR Systems. Both the Cortex-M0, and Cortex-M3 processor families are supported by the new competitively priced IAR Embedded Workbench for ARM Cortex-M toolchain.
"Ease of development and migration path within the two compatible families is the main theme at NXP" says Geoff Lees, General Manager, Microcontroller Division, NXP. "We see this as true compatibility, not just peripheral compatibility between an older 8-bit core, and a different 32-bit architecture. We are extremely pleased with IAR Systems' commitment to our new Cortex-M0 family, and are very confident of their success with this kit."
The KickStart Kit for LPC1114 contains all the necessary hardware and software for engineers to quickly design, develop, integrate and test Cortex-M0 applications. The NXP LPC111x family of devices are low-cost 32-bit MCUs designed for 8/16-bit applications and offer good performance, low power consumption, a simple instruction set and memory addressing together with small code size.
It includes a development board fitted with the LPC1114 microcontroller, an 8K KickStart edition of IAR Embedded Workbench for ARM, and a 20-state evaluation edition of IAR visualSTATE.
The board also provides debug support through IAR J-Link-OB, a standard JTAG connector or a small SWD connector. The board is powered via the USB interface, removing the need for any external power supply. It also provides some user configurable devices such as a small LCD, buttons and LEDs, analogue trim wheel, buzzer and a prototyping area. In addition, the UART pins are routed to a DB9 connector.
The J-Link-OB is a small board mounted JTAG/SWD debug interface that connects via USB to the PC host running Windows. It integrates into IAR Embedded Workbench, an Integrated Development Environment with a complete and easy-to-use set of C/C++ cross compiler and debugger tools for professional embedded applications. It contains project manager, editor, linker and librarian tools, C-SPY debugger, full integration with IAR J-Link, complete upgrade path available from IAR Systems. IAR visualSTATE is a UML-compliant graphical design environment for reactive systems, with advanced formal verification and validation tools as well as a very powerful code generator.

Microtune plans DAB SDR chip

Microtune is planning to develop a version of its software defined radio chip for the DAB standard used across Europe.
The current version supports AM/FM and HD radio but not DAB, making it a potial problem for equipment makers for the European market. The problem is that some key European countries such as Germany use the higher frequency L band. THis can be supported with a separate receiver chip, linked to the same disgial signal processor chip, still reducing the complexity and bill of materials, but not as much as a fully integrated solution.
"We have a tuner subsystem that's a discrete solution that sends data to the same DSP and the DAB data is demodulated in software on that DSP," said Peter Kipfelsberger, automotive marketing director at Microtune. "For L band it needs to be a separate tuner IC and that makes it difficult from a tuner perspective. But we are targetting a similar solution and we expect volumes to increase over the next year and we have plans to design a similar product for DAB."

SDR comes to radio and TV

Microtune has developed a chip architecture that brings Software Defined Radio (SDR) to car radios.
The MT3511 RF MicroDigitizer provides a flexible RF front end for many different standards and is coupled with a digital signal processor for a low cost implemention in a car radio.
For automotive manufacturers, software defined radio (SDR) represents a revolutionary approach to in-vehicle car entertainment, connectivity and multimedia. It enables them to flexibly deliver the most popular consumer features ­AM/FM, digital radio, CD audio, MP3 playback, navigation, as well as connectivity for iPod®, SD card, USB and Bluetooth by using common hardware that is configurable, scalable and upgradable via software. SDR solutions dramatically change ‘infotainment’ business, design and manufacturing models. This technology offers car makers a global radio platform, increased design flexibility, substantial cost-efficiencies and a future-proof migration path to new standards and enhanced features.
The MT3511 is a key front-end component in the SDR architecture. It combines the functions of a state-of-the-art RF tuner and an advanced analogue-to-digital converter in a single miniature chip­it receives and tunes a broadcast signal from a car antenna, and then converts the signal from analog to digital format for processing in software by a DSP or multimedia processor. It also supports world-standard AM/FM, HD Radio technology, digital radio mondiale (DRM), and weather band, and a DAB version with support for the higher frequency L band is being considered.
The advantage is that it replaces multiple hardware-specific components in today’s radio subsystem with a generic hardware platform that reduces design complexity, time-to-market, time-to-qualification and costs.
“For decades, leading automotive manufacturers and Tier-1 suppliers have used Microtune radio and TV tuners to migrate compelling consumer-class entertainment to the car,” said James Fontaine, President and CEO of Microtune. “We are now introducing a single-chip RF-to-digital converter that will help drive software defined radio throughout the auto industry as a practical mainstream technology. The MT3511 will be a key enabler for the future of in-vehicle audio and multimedia, while it fuels growth and opportunity for our Company across the worldwide automotive entertainment markets.”
“Software defined radio has been the holy grail of the automotive industry,” said Paul O’Donovan, analyst, Gartner Research. “While car makers have been eager to deploy the SDR concept, the baseline hardware technology required to navigate commercial cost sensitivities and the stringent automotive quality and manufacturing requirements has not been available. Modern multimedia or DSP processors are now increasing in computer power, allowing the complete processing of radio signals in software, while providing the necessary connectivity features. SDR applications also demand a new kind of front-end technology, such as the MT3511, that can receive and digitize radio broadcast signals across the fast-changing signal environment of the moving vehicle.”

Key Features

The MT3511 is characterized by very high RF-to-bits performance, a high level of integration, low cost and very low profile. With its high sensitivity, high linearity, and configurable, fully autonomous automatic gain control circuit, the MT3511 is engineered to deliver stable, clear digital intermediate frequency (IF) signals. It offers the system designer the flexibility to configure solutions for even the most challenging reception environments, while enabling high-quality radio sound and multimedia within the SDR system.
As a key feature, the MT3511 is optimized to work in the digital domain of the SDR architecture and supports on-board designs with minimal external components. It is engineered to support block-oriented processing, and combined with a patented approach for generating a manageable data rate, it frees the microprocessor to focus on other tasks, including display, connectivity, traffic management and GPS. In effect, the MT3511 enables the microprocessor to manage its resources more effectively and efficiently, a key factor in overall SDR performance.

Other features include:
· Very low phase noise
· Fully-autonomous tuning-control engine
· Integrated high-performance 16-bit ADC with self-calibration and digital error correction
· Automatic data synchronization for FM phase-diversity applications
The MT3511 is the first member of the Automotive RF MicroDigitizer family, and future products will support new digital standards with even higher levels of integration. A complete technical description is provided in the MT3511 Product Brief.
As with Microtune’s other automotive products, the MT3511 is engineered to operate in the harsh vehicular environment, meeting the unique challenges of temperature and long product-life times as compared to consumer products. Developed to meet stringent automotive specifications, it supports temperatures from -40 to +85°C, and is designed to be qualified according to the requirements of the Automotive Electronics Council (AEC) Q100.
The MT3511 is currently sampling to key customers and is priced at $3.50 in volumes of 100,000/year.

$2 TV chip

It has also developed world-standard radio frequency (RF)-to-baseband IC, based on the new architecture. The MT3141 single chip enables TV manufacturers to use a smaller, higher-performance and more cost-effective receiver across their next-generation global digital television designs. Using Microtune’s MT3141, manufacturers can build thinner, lighter digital TVs that deliver premium performance for all brands, models, price points and screen sizes.
The MT3141 is:
· A miniaturized RF-to-baseband single chip that combines the functions of an RF tuner, analog TV demodulator, intermediate frequency (IF) filters and amplifiers in a 6 mm x 6 mm IC.
· The only receiver engineered to exceed the RF performance requirements of worldwide analog/digital broadcast and cable standards*, including those for China’s new CTTB (also known as DTMB or DMB-T) and Europe’s next-generation DVB-T2 requirements.
· Tiny enough for the lightest ‘picture on a wall’ TVs, but packs the performance to put a superb TV picture on the biggest wide screen.

At $2.00 in high volumes, the MT3141 breaks through price, performance and size barriers to enable TV manufacturers finally to deploy an advanced silicon receiver in an unified high-quality front-end across all next-generation television platforms.

“Faced with increasing complexity, shrinking ASPs, divergent broadcast standards, and the need to differentiate, TV manufacturers have been looking for a new class of world-standard electronics,” said James Fontaine, President and CEO of Microtune. “Yet across all these factors, manufacturers and consumers are driven by TV picture quality. With our MT3141, manufacturers can drive world-class receiver performance into global TVs, while reducing their footprint, design effort and manufacturing costs.”

Mr. Fontaine added, “Our highly integrated receiver provides the compelling price/performance to finally fuel the TV industry migration from traditional can tuners to silicon solutions, while taking digital TV into the future.”

Unmatched Performance Based on MicroCeiver™ Architecture
Based on new MicroCeiver technology, the MT3141 is a complete RF analog and digital signal processing system in a single chip. It fuses RF tuner, analog video demodulation, filter and amplifier capabilities together, erasing the distinctions across these functional boundaries. The M3141 employs internal techniques and proprietary algorithms to continuously update information about signal conditions across the signal path, optimizing performance across the entire receiver chain.

Key performance metrics include:

* Typical noise figure: 3 dB
* Video signal to noise ratio: greater than 60 dB
* Typical sensitivity ATSC: -88 dBm
* DVB-T desired to undesired signal: exceeds NorDig 2.1 specifications by greater than 10 dB

The MT3141 receiver delivers excellent sensitivity and superior adjacent channel rejection, technical metrics that directly translate into an increase in digital TV signal coverage for broadcasters and high-quality, stable TV reception for TV viewers.

MT3141 Receiver: Dramatic Integration and Cost Reduction
A single chip, the MT3141 receives all frequencies in the 44 MHz to 1.0 GHz range. It converts a selected channel either to a low-IF or to a standard IF between 4 MHz and 57 MHz, and it outputs filtered audio (SIF) and baseband video (CVBS) signals. It is characterized by a very high level of integration with minimal external bill of materials that require no active components. The MT3141 virtually eliminates an external bill of materials.

The MT3141 complies with worldwide broadcast standards* and is engineered to exceed all performance requirements published for them, including those for legacy analog TV reception (NTSC, PAL and SECAM analog television signals for off-air and cable). The transition to digital broadcast around the world is expected to continue through at least 2018. For more technical information about the MT3141, please read the MT3141 Product Brief.

Global automotive telematics market to quadruple

Boom time as 68m cars ship with telematics by 2016

Global shipments of automotive telematics systems are set to rise to 84.4 million units in 2016, up by a factor of more than four from 19.3 million in 2008, according to iSuppli.
“From sending out an automatic distress call after a car crash, to enabling remote diagnosis of engine troubles, telematics can provide enormous benefits to motorists and car makers around the world,” said Anna Buettner, analyst with iSuppli’s automotive research service. “For drivers, telematics can enhance safety, convenience and connectivity. For car OEMs, telematics can add to and improve car functionality and reduce warranty and after-sales costs. That’s why carmakers and consumers are expected to increase their adoption of telematics systems rapidly during the next seven years.”
By 2016, 68.4 million cars will ship with telematics systems installed by OEMs, up from 14.3 million in 2008. This means that 84.6 percent of all cars shipped in 2016 will incorporate telematics systems.
Aftermarket shipments of telematics systems will rise to just under 16 million units in 2016, up from slightly less than 5 million in 2008.
Beyond accident alerts and remote diagnosis, telematics functions span from the wireless integration of third-party devices, to navigation and Location-Based Services (LBS) updates, to theft detection, to engine control software revisions.
The United States is the world’s leading market for telematics in 2009, with 30 percent of all models sold in the country available with installed systems. In comparison, the next two biggest telematics nations, Germany and Italy, have only 20 percent model availability of installed telematics systems.
The U.S. leadership is due to General Motors (GM), which pioneered installed telematics in 1996 with its OnStar service. The company has made OnStar a standard feature on all its cars this year.
“With GM selling 2 million cars with installed telematics per year, competitors have been forced to react,” Buettner said. “In the intervening years, Ford, BMW, Mercedes-Benz, Honda, Nissan and Toyota all launched telematics systems.”
Western European telematics volume remains low because no major OEM in the region has made the feature standard on every car. Japan also is deploying telematics in low volumes, and the applications are focused on navigation functionality and infotainment.
However, as telematics becomes more available in other regions, U.S. domination will dwindle. The United States in 2009 accounts for about half of the global installed OEM telematics market. By 2016, the United States will account for about one third of the worldwide market as shipments in other regions soar.

Embedded v. mobile device telematics

Two major types of telematics solutions are being offered on the market: embedded systems, whose functionality is integrated into the headunit of cars; and mobile-device oriented systems, which use a wireless product like a cell phone to communicate information.
Both embedded and mobile device telematics systems are on rapid growth paths. Worldwide OEM embedded telematics systems will grow from nearly 4.8 million units in 2008 to more than 26.8 million systems in 2016.
Meanwhile, global OEM mobile device telematics systems will grow from 9.5 million units in 2008 to more than 41.5 million systems in 2016.

WiFi and Coldfire on embedded tower development system

Modular development platform helps save months of development time through rapid prototyping and tool re-use

Freescale Semiconductor has launched a rapid evaluation and prototyping development system with two interchangeable peripheral modules and 8- and 32-bit microcontroller (MCU) modules for the Tower System.
The advanced peripheral modules offer developers 802.11b Wi-Fi and rapid prototyping functionality while the newest MCU modules support Freescale’s MCF5225X 32-bit ColdFire MCU and MC9S08LL64 8-bit MCU.
"With the addition of these advanced modules for Freescale’s Tower System, we are providing designers, students and hobbyists an affordable development system that’s modular and expandable,” said Aiden Mitchell, director of Freescale’s Industrial & Multi-Market Microcontroller business. “The Tower system, in conjunction with Freescale MQX software, is the ultimate enablement solution – giving designers an array of building blocks for entry-level to advanced processor development and helping speed time to market.”
The Tower System provides a comprehensive and highly customisable embedded design environment that allows developers to mix and match MCU and peripheral boards to create reconfigurable development platforms that suit their design needs. Interchangeable modules promote reuse of hardware across multiple architectures, which helps speed time to market. The modular design scales down overall tool costs, while providing an inexpensive entry point.

Advanced MCU modules

The Tower System now supports two advanced microcontroller modules: the TWR-MCF5225X and the TWR-S08LL64, featuring the ColdFire V2 MCF5225X MCU and the 8-bit MC9S08LL64 MCU, respectively. These modules can be combined with various peripheral modules to form a unique Tower System development tool or used as standalone debug tools.
The TWR-MCF5225X offers a powerful and flexible industrial connectivity solution with on-chip USB, Ethernet, controller area network (CAN) and encryption, along with the Freescale MQX real time operating system and associated tools and software stacks. The 8-bit MC9S08LL64 MCU includes an on-chip LCD driver that supports up to eight backplanes, enabling developers to drive more segments with fewer pins, reducing system cost and design complexity. The S08LL family supports an LCD blink mode that operates without waking up the controller core, which helps reduce overall power consumption.
These advanced modules complement the previously announced TWR-MCF51CN Ethernet MCU module.

WiFi peripheral modules

The Wi-Fi module (TWR-ZGWIFI) adds 802.11b Wi-Fi functionality to the Tower System and includes the ZeroG Systems ZG2100 Wi-Fi I/O module and antenna, as well as configuration jumpers and an RS232 debug port. The embedded Wi-Fi module from ZeroG is optimised for embedded applications, with low data rates, power consumption and system resource requirements. The TWR-ZGWIFI module is FCC-certified and offers seamless integration with Freescale’s MQX software solution. With this module, developers can easily add Wi-Fi connectivity and run sample applications using the kit in less than a few hours.
The prototyping module (TWR-PROTO) allows designers to quickly add custom circuitry and build custom prototype boards with application-specific features. With ample perfboard area, this cost-effective module is ideal for hardware development and testing during system design.
These two peripheral modules complement the previously announced serial module (TWR-SER), supporting Ethernet, USB, RS232, RS485 and CAN, and elevator modules (TWR-ELEV) that connect the MCU and peripheral boards.
The Tower System’s easy-to-use, modular design helps customers control tool costs, from simple concept testing to full product development. A single MCU/MPU module serves as the main control board. Modules simply plug into backplane boards, called “elevators,” through standard PCB edge connectors. Peripheral board re-use eliminates the need to buy and develop redundant hardware, which reduces future costs. In addition, the MCU modules include open-source background debug mode (OSBDM) hardware, allowing each board to serve as a standalone debug tool.
Tower modules are currently available for MCF51CN, MCF5225X and MC9S08LL64 MCUs. In future months, Freescale and its partners plan to provide Tower System support for additional embedded devices, including other ColdFire MCUs, 8-bit MCUs and digital signal controllers (DSCs).
