Silicon Image said on Monday that it has developed the industry's first single-chip, ultra-low power 60 GHz WirelessHD mobile transmitter for smartphones and tablets. Called the UltraGig 6400, this chip integrates a 60 GHz RF transceiver, baseband processor, and embedded antenna array into a single IC package. The result is a chip that can wirelessly send high-definition video from a mobile device to a large WirelessHD-compliant display via a cable-like connection, but without the annoying wires.
The chip's 60 GHz RF transceiver employs beamforming, or spatial filtering, a technique used for directional signal transmission and reception. The majority of a signal's energy transmitted from a compatible device is directed in a chosen angular path. Tom's William Van Winkle said it best back in 2009: "you’re controlling the output characteristics of each transmitter within a transmitter array so that the overall signal is optimized to reach a given receiver in a given direction."
Silicon Image said the chip's integrated high-performance baseband network processor ensures that high-quality HD video can be transmitted with near-zero latency (less than 5ms) and without consuming host processor resources. It also not only has a low-power profile, but measures an ultra-small 10-mm x 7-mm, simplifying system integration while eliminating the need for discreet antenna placement.
The new Silicon Image chip includes support for video resolutions up to 1080p full HD with multi-channel audio, full compatibility with Silicon Image Gen3 and all WirelessHD 1.1 compliant receivers, and standard video and control interfaces to popular mobile application processors. This complete WirelessHD solution, according to the company, is ideal for for mobile gaming and interactive video applications.
"By offering superior performance in an ultra-small form factor package, the UltraGig 6400 establishes a new benchmark for mobile HD video wireless connectivity," said Jim Chase, director of marketing of the wireless division at Silicon Image, Inc. "Mobile devices powered by the UltraGig 6400 will be able to take advantage of a cable-like wireless video connection to other devices in the growing WirelessHD ecosystem."
The UltraGig 6400 mobile 60 GHz WirelessHD transmitter is currently sampling to mobile device manufacturers.
