Si2167-D60
The Si2167D integrates digital demodulators for first and second
generation DVB standards (DVB-T/C/S/S2 and S2X) in a single
advanced CMOS die. Leveraging Silicon Labs' proven digital
demodulation architecture, the Si2167D achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2167D to a hybrid TV tuner or digital
only tuner, such as Silicon Labs' Si217x/5x/4x devices, results in a
high-performance and cost optimized TV or STB front-end
solution.
DVB-T and DVB-C demodulators are enhanced versions of
proven and broadly used Si2169/68/67/64/62/60 Silicon Labs
devices. Furthermore, ITU-T 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 reception allows demodulating widespread DVB-S,
DIRECTV™ (DSS), DVB-S2, DIRECTV™ (AMC) legacy
standards, and new Part II of DVB-S2 (S2X) satellite broadcast
standard. A zero-IF interface (differential) allows for a seamless
connection to market proven satellite silicon tuners. Si2167D
embeds DiSEqC
TM
2.0 LNB interface for satellite dish control and
an equalizer to compensate for echoes in long cable feeds from
the antenna to the satellite tuner input.
The Si2167D offers an on-chip blind scan algorithm for DVB-S/S2/
S2X and DVB-C standards, as well as a blind lock function. The
Si2167D programmable transport stream output 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.
