dual digital demodulators copyright ? 2015 by silicon laboratories 11.5.15 SI21672-D60 dual dvb-s2/s2x/t/c/s digital tv demodulator description the si21672d integrates two sepa rate high-performance digital demodulators for the dvb-t/c, dvb-s2/s and dvb-s2x standards into a single compac t package. leveraging silicon labs' proven digital demodulation archit ecture, the si21672d achieves excellent reception performance fo r each media while significantly minimizing front-end design co mplexity, cost, and power dissipation. connecting the si21672d to both a dual terrestrial/ cable tv tuner, and a dual satellite tuner, results in a high-performance and cost optimized tv front-end solution. the dvb-t and dvb-c, including itu-t j.83 annex b, demodulators ar e enhanced version s of proven and broadly used si2164/67/68/69 sili con labs devices. the satellite reception allows de modulating widespread dvb-s, directv? (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. it also integrates two diseqc? 2.0 lnb interfaces for satellite dish control and, for each satellite demodulator, an equalizer to compensate for echoes in long cable feeds from the lnb to the satellite tuner rf input. the si21672d offers an on-chip blind scanning algorithm for dvb-s/s2/s2x and dvb-c st andard s, as well as blind lock function. the si21672d embeds two independent programmable transport str eam inter faces which provide a flexible range of output modes, including a cross-bar functionality, and are fully compatible with all mpeg decoders or conditional ac cess modules to support any customer application. features - pin-to-pin compatible with al l dual demodulator family: si216x2 and si218x2 - api compatible with all single and all dual demodulators - dvb-t (etsi en 300 744) - nordig unified 2.5, d-book 8 compliant - dvb-c (etsi en 300 429) / itu-t j.83 annex a/b/c - 1 to 7.2 msymbol/s, c-book compliant - 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 - channel bonding for ts transmission supported - dvb-s (etsi en 300 421) and dss supported - dual diseqc? 2.x interface, unicable support - 1 to 45 msps for all satellite standards ?
