(dss), dvb-s2, directv? (amc) legacy standards, and new part ii of dvb-s2 (s2x) satellite broadcast standard. a zero-if interface (differential) allows for a seamless connection to market proven sate llite silicon tuners. si2164c embeds diseqc tm 2.0 lnb interface for satellite dish control and an equalizer to compensate for echoes in long cable feeds from the antenna to the satellite tuner input. the cable reception allows demodulating widely deployed dvb-c leg a cy standard (itu-t j.83 annex a/c) and the americas' cable standard (itu-t j.83 annex b). the si2164c offers an on-chip blind scan algorithm for dvb-s/s2/ s2x and dvb-c st andards, as well as a blind lock function. the si2164c programmable transport stream output interface provides a flexible range of output modes and is fully compatible with all mpeg decoders or conditional ac cess modules to support any customer application. features - pin-to-pin compatible with al l si216x/8x single demods family - api compatible with all single and dual demods families - dvb-t2 (etsi en 302 755-v1.4.1) with t2-lite (annex i) - bandwidth: 1.7, 5, 6, 7, and 8 mhz - nordig unified 2.5 and d-book 8 compliant - dvb-c2 (etsi en 302 769-v1.2.1) - 16-qam to 4096-qam ofdm demodulation - dvb-s2 (etsi en 302 307-1 v1.4.1) - qpsk/8psk demodulator - dvb-s2x (etsi en302 307-2 v1.1.1) - qpsk/8psk, 8/16/32apsk demodulator - roll-off factors from 0.05 to 0.35 - dvb-t (etsi en 300 744) - ofdm demodulator and enhanced fec decoder - nordig unified 2.5 and d-book 8 compliant - dvb-c (etsi en 300 429) and itu-t j.83 annex a/b/c - qam demodulator and fec decoder - 1 to 7.2 msymbol/s - dvb-s (etsi en 300 421) and dss supported - qpsk demodulator and enhanced fec decoder - 1 to 45 msymbol/s for all satellite standards (<40 msps in 32apsk) - ldpc and bch fec decoding for c2/t2 and s2 standards - i 2 c serial bus interfac es (master and host) - firmware control (embedded rom/nvm) - upgradeable with patch download via fast spi or i 2 c ?
