Dual DVB-S/S2 Digital TV Demodulator
Description
The Si21662-B integrates two separate high performance
DVB-S, DVB-S2 and DSS digital demodulators into a single
compact package for satellite TV standards. Leveraging
Silicon Labs' proven digital demodulation architecture, each
embedded demodulator achieves excellent reception
performance for each standard while significantly minimizing
front-end design complexity and cost. Connecting the
Si21662-B to a dual satellite tuner, results in a
high-performance and cost optimized TV front-end solution.
The satellite demodulation functionality allows demodulating
widely deployed DVB-S, DIRECTV™ (DSS) legacy
standards, and DVB-S2 (AMC compliant) satellite broadcasts.
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 Si21662-B offers an on-chip blind scanning algorithm for
DVB-S/S2 standards. It also integrates two DiSEqC™ 2.0
LNB interfaces for satellite dish control and, for each satellite
demodulator, an equalizer to compensate for echoes in long
cable feeds from the LNB to the satellite tuner RF input.
The Si21662-B embeds two independent programmable
transport stream interfaces which provide a flexible range of
output modes and are fully compatible with all MPEG
decoders or conditional access modules to support any
customer application.
