MILPITAS, Calif. -- LSI Logic Corp. here today unveiled a next-generation single-chip demodulator aimed at the digital terrestrial TV market, an emerging technology in Europe.
Based on its L64780 predecessor, LSI Logic's L64781 integrates forward error correction, 10-bit analog-to-digital converter (ADC) and demodulator blocks, all in a small 100-pin package with low power consumption.
Digital terrestrial TV (DTT) has been highly successful in the U.K and in Sweden and is soon to be rolled out in the Spanish market, according to Elie Antoun, executive vice president of LSI Logic's Consumer Products Division. LSI Logic worked closely with the BBC Research and Development labs in the U.K on the chip's development.
"While other solutions fall short of industry performance benchmarks, our second generation, true single-chip, solution will enable LSI Logic to maintain its position as the dominant player in this market," Antoun said.
Set-top boxes and integrated digital TVs receive DTT broadcasts with an antenna, but rely on demodulator chips to "translate" these signals into the higher-quality sound and images for digital TV. In addition, because many more channels can be broadcast digitally, the demodulator must eliminate interference and noise.
The L64781's high-performance enhance reception capability without requiring additional antennas, and offers broadcasters wider coverage and lower-power transmissions, LSI Logic said.
The chip also has excellent mobile reception capabilities, and has been proven to work at speeds of up to 200 kilometers per hour, according to the company.
Ian Childs, head of research at BBC R&D, said, "We have estimated that the increased sensitivity and robustness of the new chip could increase the potential number of Britons able to receive the channels carrying digital television broadcasts by more than 1 million viewers."
L64781 samples, together with an evaluation daughter board for the set-top box development platform, are available now. The chip is priced below $17 in volume.
