Si2167-D60
DVB-T/C/S/S2/S2X Digital TV Demodulator
Description
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.
