The L64781 has consequently achieved better performance levels, especially in the area of co-channel interference. The co-channel immunity of the L64781 is such that, in certain modes, it is possible to receive a perfect digital picture even in the presence of a strong analogue signal on the same frequency. The analogue signal, on the other hand, offers a viewable, if somewhat snowy picture, on a conventional analogue TV set. End-users benefit from enhanced reception capability without requiring additional antennas.
Broadcasters gain the benefits of wider coverage or lower power transmissions.
In addition, as many more channels can be broadcast digitally than with previous analogue broadcasts, it is critical that the demodulator chip effectively eliminates interference and noise to deliver optimum performance. Broadcasters and viewers can expect to see improvements in both coverage and reception. Digital terrestrial TV has been hugely successful in the UK and in Sweden and is soon to be rolled out in the Spanish market. 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. The evaluation board includes the L64781 device, software drivers and a tuner module.
