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. The Si2166-B22 programmable Transport Stream 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. Si2166-B22 is fully API compatible with Si2164/69/68/67.
