Si2164-C60
DVB-T2/C2/S2/S2X/T/C/S Digital TV Demodulator
Description
The Si2164C integrates digital demodulators for all first and
second generation DVB standards (DVB-T/T2/C/C2/S/S2 and
S2X) in a single advanced CMOS die. Leveraging Silicon Labs'
proven digital demodulation architecture, the Si2164C achieves
excellent reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2164C 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.
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-T2/T, DVB-C2/C and DVB-S2/S demodulators are
next-generation enhanced versions of proven and broadly-used
Silicon Labs’ Si2169/68/67/66/64/62/60 devices. DVB-T2-Lite
(ETSI EN 302 755-V1.3.1) compatibility is also supported.
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. Si2164C
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 cable reception allows demodulating widely deployed DVB-C
legacy standard (ITU-T J.83 Annex A/C) and the Americas' cable
standard (ITU-T J.83 Annex B).
The Si2164C offers an on-chip blind scan algorithm for DVB-S/S2/
S2X and DVB-C standards, as well as a blind lock function. The
Si2164C 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.
