DVB Demodulator for DVB-C2/C/T/S/S2
Description
The Si2160 integrates digital demodulators for the first and second
generation DVB video broadcasting standards (DVB-C2/S2/T/C/S)
in a single advanced CMOS die. Leveraging Silicon Labs' proven
digital demodulation architecture, the Si2160 achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2160 to a terrestrial and cable hybrid
TV tuner or digital only tuner, such as Silicon Labs' Si2178/58/48
devices, results in a high-performance and cost optimized TV
front-end solution.
Silicon Labs' internally developed DVB-C2 demodulator can
accept a standard IF (36 MHz) or low-IF input (differential) and
support all modes specified by the DVB-C2 standard. The main
features of the DVB-C2 mode are 4096-QAM, 6 or 8 MHz
bandwidth, management of notch insertion (broadband and
narrowband), and support of multiple data slices and PLPs.
DVB-C and DVB-S/S2 demodulators are enhanced versions of
proven and broadly-used Silicon Labs Si2169/68/67/66 devices.
The satellite demodulation functionality allows demodulating
widely deployed DVB-S, DIRECTV
TM
(DSS) legacy standards,
and new generation DVB-S2 (AMC compliant) satellite
broadcasts. A zero-IF interface (differential) allows for a seamless
connection to market proven satellite silicon tuners. The Si2160
embeds DiSEqC
TM
2.0 LNB interface for satellite dish control and
an equalizer to compensate for echoes in long cable feeds from
antenna to the satellite tuner input.
The cable demodulation functionality allows demodulating widely
deployed DVB-C legacy standard (ITU J.83 Annex A/C) and
Americas' cable standard (ITU J.83 Annex B).
The Si2160 offers an on-chip blind scan algorithm for DVB-S/S2
and DVB-C/C2 standards, as well as a blind lock function. The
Si2160 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.
