Si2166-B22 DVB-S/S2 Satellite TV Demodulator Description Features - DVB-S2 (ETSI EN 302 307 and TR102-376) - QPSK/8PSK demodulator and FEC decoder - Broadcast profile: CCM, 64800 bits frame, single TS - 1 to 45 MSymbol/s (optimized for 2 to 32 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 - I2C serial bus interfaces (master and host) - Two ADCs with differential inputs (ZIF input) - GPIOs and multi-purpose ports for independent AGCs The Si2166-B22 integrates DVB-S, DVB-S2 (AMC-compliant), and DSS digital demodulators into a single CMOS chip for the broadest range of satellite TV standards. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2166-B22 achieves superior satellite reception performance while minimizing front-end design complexity and cost. The satellite demodulation functionality allows demodulating widely deployed DVB-S, DIRECTV™ (DSS) legacy standards, and DVB-S2 satellite broadcast. A zero-IF interface with two high-speed ADCs allows for a seamless connection to market proven satellite silicon 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. - For DVB-S/DSS standards, an innovative and advanced FEC decoding scheme is implemented resulting in higher performance. The Si2166-B22 offers an on-chip blind scanning algorithm for DVB-S and DVB-S2 standards (as well as blind lock function). It also integrates DiSEqC™ 2.0 LNB interface for satellite dish control.
