(dss) legacy standards, and dvb-s2 satellite broadcast. a zero-if interface allows for a seamless connection to market proven satellite silic on tuners. constant coding modulation (ccm), qpsk/8psk demodulation schemes and broadcast profile are the main specifications of the dvb-s2 demodulator. silicon labs' innovative ldpc and bch decoding architecture delivers best-in-class reception while exhibiting low power dissipation. the SI2167-B22 offers an on-chip blind scanning algorithm fo r dvb-s/s2 and dvb-c standards (as well as blind lock function). it also integrates diseqc? 2.0 lnb interface for satellite dish control. the SI2167-B22 programmable transport stream interface provid es a flexible range of output modes and is fully compatible with all mpeg decoders or conditional access modules to support any customer application. SI2167-B22 is fully api compatible with si2164/69/68/66. features - dvb-t (etsi en 300 744) - cofdm demodulator and enhanced fec decoder - supports all c.r., g.i., lp, and hp streams - nordig test spec 2.2.2, d-book 7 v3 compliant - dvb-c (etsi en 300 429) / itu j.83 annex a/b/c - qam demodulator and fec decoder - 1 to 7.2 msymbol/s - c-book compliant - dvb-s2 (etsi en 302 307 & tr102-376) - qpsk/8psk demodulator and fec decoder - broadcast profile: ccm, 64800 bits frame, single ts - 1 to 45 msymbol/s - directv? amc compatible - dvb-s (etsi en 300 421) - qpsk demodulator and enhanced fec decoder - 1 to 45 msymbol/s - directv? dss supported - diseqc? 2.0 interface and unicable support - i 2 c serial bus interfaces (master and host) - three adcs with independent if and zif (differential) inputs for terrestrial/cable and satellite - gpios and multi-purpose ports for independent agcs (up to 4) to control satellite and t/c tuners - firmware control for upgradeability - flexible ts interface with serial or parallel single output - fast lock times for all media - only two power supplies: 1.2 and 3.3 v - pin-to-pin and api compatibility with ? si2164/69/68/66 - 7x7 mm, qfn-48 pin package, pb-free/rohs compliant applications - full-nim - idtv (integrated digital tv) - digital terrestrial, cable, and satellite stb - pc-tv accessories - pvr, dvd, and blue ray disc recorders
