The Si2167-B20 integrates DVB-T, DVB-C, DVB-S, DVB-S2 (AMC-compliant), and DSS digital demodulators into a single
CMOS chip for terrestrial, cable, and satellite TV standards. Leveraging Silicon Labs' proven digital demodulation architecture,
the Si2167-B20 achieves superior reception performance for each media while minimizing front-end design complexity and cost.
Connecting the Si2167-B20 to a terrestrial and cable hybrid TV tuner, such as Silicon Labs’ Si217x, results in a high
performance and cost optimized TV front-end solution.
DVB-T and DVB-C demodulators are enhanced versions of proven and broadly used Si2167-A10 and Si2169/68 Silicon Labs
devices. Furthermore, ITU J.83 Annex B is also supported for US and South American cable networks. The IF input supports
standard IF (36 MHz) or low-IF.
For DVB-T and DVB-S/DSS, an innovative and advanced FEC decoding scheme is implemented resulting in higher
performance.
The satellite demodulation functionality allows demodulating widely deployed DVB-S, DIRECTV™ (DSS) legacy standards,
and new generation DVB-S2 satellite broadcast. A zero-IF interface 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.
The Si2167-B20 offers an on-chip blind scanning algorithm for 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.
