DVB-S/S2 Satellite TV Demodulator
Description
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.
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.
