Universal DVB Demodulator for DVB-T2/C2/S2/T/C/S
Description
The Si2164 integrates digital demodulators for all of the first and
second generation DVB video broadcasting standards (DVB-T2/
C2/S2/T/C/S) in a single advanced CMOS die. Leveraging Silicon
Labs' proven digital demodulation architecture, the Si2164
achieves excellent reception performance for each media while
significantly minimizing front-end design complexity, cost, and
power dissipation. Connecting the Si2164 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-T/T2, DVB-S/S2 and DVB-C demodulators are enhanced
versions of proven and broadly-used Silicon Labs Si2169/68/67/66
devices. DVB-T2-Lite (ETSI EN 302 755-V1.3.1) compatibility is
also supported as an added feature to the DVB-T2 standard.
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. Si2164
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 Si2164 offers an on-chip blind scan algorithm for DVB-S/S2
and DVB-C/C2 standards, as well as a blind lock function. The
Si2164 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.
