TV receiver platform fits China digital broadcast standard

Analog Devices has collaborated with Legend Silicon to accelerate the development of mobile TV receivers for China with what the company is calling the industry's first digital TV standard-compliant receiver solution. The new digital terrestrial TV broadcasting standard, coded GB 20600-2006, will come into effect on August 1, 2007.

Coupling demodulators from Legend with low-power RF tuners from ADI's Integrant Technologies will enable customers to integrate digital reception into a range of portable devices, including portable media players, PDAs, and smart phones.

Legend Silicon's demodulator was designed from the ground up to provide services for both fixed terrestrial HDTV and mobile broadcasts. Based on TDS-OFDM (time domain synchronous – orthogonal frequency division multiplexing) technology, this solution provides continuous reception in the challenging conditions mobile applications present, as well as accommodating fixed applications in urban environments comprised of severe multipath interference.

The joint demonstration platform meets the low-power, performance, and time-to-market requirements that will be needed to support digital reception in portable platforms. Battery efficiency, small form factors, and lower-cost solutions are enabled by the low-power RF tuner, which will support mobile extensions and applications of the Chinese digital broadcast standard.
