Description
The Si21672-B integrates two separate high-performance
DVB-T, DVB-C, DVB-S, and DVB-S2 digital demodulators into
a single compact package for terrestrial, cable, and satellite
TV standards. Leveraging Skyworks' proven digital
demodulation architecture, each embedded demodulator
achieves excellent reception performance for each media
while significantly minimizing front-end design complexity and
cost. Connecting the Si21672-B to both a dual
terrestrial/cable TV tuner, and a dual satellite tuner, results in
a high-performance and cost optimized TV front-end solution.
The DVB-T and DVB-C demodulators are enhanced versions
of proven and broadly used Si2167/68/69 Skyworks 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.
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.
The Si21672-B offers an on-chip blind scanning algorithm for
DVB-S/S2 and DVB-C standards (as well as blind lock). 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 Si21672-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.
