TI claims industry's fastest 16bit DAC

Texas Instruments has unveiled the industry’s fastest 16-bit digital-to-analogue converter (DAC) running at 2.5Gsamples per second with a four channel version providing 2GHz of information bandwidth for basestation and signal processing applications.

The DAC38J84 and DAC38J82 provide the bandwidth, performance, small footprint and low power consumption needed for multi-mode 2G/3G/4G cellular base stations to migrate to more advanced technologies, such as LTE-Advanced and carrier aggregation on multiple antennas. The DACs support up to 2 GHz of information bandwidth for wideband power amplifier digital pre-distortion, millimeter wave backhaul infrastructure, signal jamming, radar and test equipment.

Tool debugs deeply embedded multicore SoC devices

Debugging multicore devices in deeply embedded systems is a key problem for designers. PLS Programmierbare Logik & Systeme has launched the latest version of its Universal Debug Engine (UDE) 4.2 with enhanced control and test methods for a wide range of 32bit multicore System on Chip (SoC) targets and optimized visualisation options during system level testing.

Individual cores can be specifically selected and also synchronized for control by the debugger. This also includes the extensive use of existing on-chip trigger and synchronization options of various device manufacturers. With the UDE 4.2, the consistent user interface ensures the greatest possible flexibility when controlling a multicore target, without the need to know the underlying on-chip logic in detail.
The trace framework of the Universal Debug Engine 4.2 has also been equipped with numerous new features. For example, relocation of the data processing in a separate process not only increases the speed of the evaluation, but also allows persistent storage of trace sessions for analysis at a later time without direct access to the target. Furthermore, comprehensive filters and the possibility to individually color recorded events of various trace sources simplify a clear presentation of the results.
An enhancement of the proven Universal Emulation Configurator (UEC) of the Universal Debug Engine (UDE) ensures an even more efficient use of the emulation devices offered by Infineon, Freescale and STMicroelectronics for some SoCs. Programming of the additional trigger logic contained on the emulation devices is performed by a graphical configuration of trace tasks, by which signals and actions are linked via a state machine.

Ultrasonics slash cost of gas sensors

Ultrasonics slash cost of gas sensors:  A gas sensor using ultrasonic measurements is set to slash the cost of medical monitoring.

The new ultrasonic sensor uses patent-pending technology developed by TTP in Cambridge to precisely measure the speed of sound in a gas to determine its composition. While current infrared gas sensing devices for carbon dioxide can cost over £240 and paramagnetic systems for oxygen around £120, TTP believes that its new SonicSense devices will cost between £3 and £6 each in volume production. Potential medical applications include respiratory monitoring, anaesthesia and heart monitoring.
