Description

The Si2166-B22 integrates DVB-S, DVB-S2 (AMCcompliant),

and DSS digital demodulators into a single

CMOS chip for the broadest range of satellite TV

standards. Leveraging Skyworks' 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. Skyworks'

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.
