Silicon Image Launches Third-Generation WirelessHD 60GHz Chipsets

Transmission of Uncompressed HD Video and Audio targets mobile devices

By Nick Flaherty

Hot on the heels of its acquisition of SiBeam, Silicon Image is launching a third generation 60GHz WirelessHD chipset for high speed HD video applications. 
The SiI6300 family consists of the SiI6320 HRTX Network Processor, SiI6321 HRRX Network Processor and SiI6310 HRTR RF Transceiver and place the company at the forefront of delivering true uncompressed and lossless 1080p Full HD audio and video via a cost-effective, end-to-end wireless video solution for consumer electronics (CE), personal computing (PC) and mobile applications. The chipset is designed to support the latest WirelessHD 1.1 features including support for 1080p/60, 36-bit Deep Colour video, all 3D formats and a host of link robustness improvements. It is also designed to be more cost-effective and lower power, and to feature a smaller form-factor compared to the previous generation SB9200. Each chipset will include a Network Processor and an RF Transceiver.
“Silicon Image continues to expand its 60GHz wireless solution for audio, video and now data transmission with robust third-generation, WirelessHD-compliant chipsets,” said John LeMoncheck, vice president and general manager of the wireless division at Silicon Image and former CEO of SiBeam. “Building on a production-proven platform combined with new feature enhancements, the SiI6300 family is designed to lower the overall system cost of adding WirelessHD by up to 50% compared to the previous generation. Products integrating the SiI6300 chipset family with WirelessHD technology will enable consumers to seamlessly connect multiple devices to a display over a full wireless video area network.”
The SiI6320 HRTX Network Processor and the SiI6310 HRTR RF Transceiver are targeted for design into mobile devices such as notebook PCs and tablets as well as CE devices including A/V receivers, home theater-in-a-box systems, Blu-ray Disc players and set-top boxes while the SiI6321 HRRX Network Processor and the SiI6310 HRTR RF Transceiver are targeted for integration into DTVs, PC monitors and front projectors.

New WirelessHD 1.1 features to be supported by the SiI6300 family include:
  • New medium rate PHY (MRP) support for more robust wireless performance
  • 5 low rate PHY (LRP) channels for each high rate PHY (HRP) channel allowing more wireless video area networks (WVANs) to be co-located in close proximity
  • Ability to transmit 1080p/60, Deep Color and 3D content
  • Bi-directional 1Gbps data link
The features expected to help lower overall system cost include cost-effective organic RF packaging for the SiI6310, an integrated buck converter controller for lower cost, higher efficiency modules, an integrated HDMI Audio Return Channel compatible with LR-Audio and smaller form factor packaging and lower power consumption for mobile devices.
Silicon Image’s WirelessHD chipsets embed OmniLink60 advanced adaptive beam-forming technology providing robust operation over 10m in non-line of sight (NLOS) conditions. New power savings features automatically adjust output power for optimal performance when operating or to lower power states when the chipset is not actively transmitting thereby maximizing power savings for mobile applications. By operating at 60GHz, the chipsets are designed not to suffer interference issues seen with other wireless audio/video solutions based on 2.4GHz and 5GHz.
The SK6300 WirelessHD Development Kits will be available for CE, PC and mobile manufacturers to integrate WirelessHD into their next-generation product lines. The development kits include manufacturing-ready WirelessHD modules as well as full documentation including the user guide, schematics, bill of materials, Gerber files, and reference firmware.
