STV0196B QPSK/BPSK DEMODULATOR AND FEC IC

Designed for the fast growing direct broadcast satellite (DBS) digital TV receiver market, the SGS-THOMSON STV0196B Digital Satellite Receiver Front-end integrates all the functions needed to demodulate incoming digital satellite TV signals from the tuner : Nyquist filters, QPSK/BPSK demodulator, signal power estimator, automatic gain control, Viterbi decode.

Features

demodulator, signal power estimator, automatic gain control, Viterbi decoder, deinterleaver, ReedSolomon decoder and energy dispersal descrambler. This high level of integration greatly reduces the package count and cost of a set top box. The demodulator blocks are suitable for a wide range of symbol rates while the advanced error correction functions guaranteea low error rate even with small receiver antennas or low power transmitters. The STV0196B has multistandard capability. It is fully compliant with the recently defined Digital Video Broadcasting (DVB) standard (already adopted by satel.
