Si2160 Digital DVB-C2 TV Demodulator
2Pages

The satellite demodulation functionality allows demodulating widely deployed DVB-S, DIRECTVTM (DSS) legacy standards, and new generation DVB-S2 (AMC compliant) satellite broadcasts. A zero-IF interface (differential) allows for a seamless connection to market proven satellite silicon tuners. The Si2160 embeds DiSEqCTM 2.0 LNB interface for satellite dish control and an equalizer to compensate for echoes in long cable feeds from antenna to the satellite tuner input. The cable demodulation functionality allows demodulating widely deployed DVB-C legacy standard (ITU J.83 Annex A/C) and Americas' cable standard (ITU J.83 Annex B).

The Si2160 programmable transport stream output interface provides a flexible range of output modes and is fully compatible with all MPEG decoders or conditional access modules to support any customer application. - DVB-C2 (ETSI EN 302 769) - 16-QAM to 4096-QAM OFDM demodulation - 6 MHz and 8 MHz bandwidth - Notch management - DVB-S2 (ETSI EN 302 307 and TR102-376) - QPSK/8PSK demodulator - 1 to 45 MSymbol/s - DVB-C (ETSI EN 300 429) and ITU J.83 Annex A/B/C - QAM demodulator and enhanced FEC decoder - 1 to 7.2 MSymbol/s - DVB-T (ETSI EN 300 744) - OFDM demodulator and enhanced FEC decoder - Nordig Unified 2.4 and D-Book 7 V2 compliant - DVB-S and DSS - QPSK demodulator and enhanced FEC decoder - 1 to 45 MSymbol/s - LDPC and BCH FEC decoding for C2 and S2 standards - I2C serial bus interfaces (master and host) - Firmware control for upgradeability - Flexible TS output interface (serial, parallel, and slave) - DiSEqCTM 2.0 interface and Unicable support for satellite - Fast lock times for all media - Low power consumption - Two power supplies: 1.2 and 3.3 V - 7x7 mm, QFN-48 pin package, Pb-free/RoHS compliant - Pin-to-pin and API compliant with Si2166/67/68/69/62/64 TS_SYNC TS_VAL TS_CLK TS_DATA 8 Silicon Labs' internally developed DVB-C2 demodulator can accept a standard IF (36 MHz) or low-IF input (differential) and support all modes specified by the DVB-C2 standard. The main features of the DVB-C2 mode are 4096-QAM, 6 or 8 MHz bandwidth, management of notch insertion (broadband and narrowband), and support of multiple data slices and PLPs. DVB-C and DVB-S/S2 demodulators are enhanced versions of proven and broadly-used Silicon Labs Si2169/68/67/66 devices. The Si2160 integrates digital demodulators for the first and second generation DVB video broadcasting standards (DVB-C2/S2/T/C/S) in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2160 achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2160 to a terrestrial and cable hybrid TV tuner or digital only tuner, such as Silicon Labs' Si2178/58/48 devices, results in a high-performance and cost optimized TV front-end solution.
