Si2160-C60
DVB-C2/S2/S2X/T/C/S Digital TV Demodulator
Description
Features
The Si2160C integrates digital demodulators for all first and
second generation DVB standards (DVB-T/C/C2/S/S2 and S2X) in
a single advanced CMOS die. Leveraging Silicon Labs' proven
digital demodulation architecture, the Si2160C achieves excellent
reception performance for each media while significantly
minimizing front-end design complexity, cost, and power
dissipation. Connecting the Si2160C 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 (ETSI EN 300 744)
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-S and DSS supported
next-generation enhanced versions of proven and broadly-used
Silicon Labs’ Si2169/68/67/66/64/62/60 devices.
- QPSK demodulator and enhanced FEC decoder
1 to 45 MSymbol/s for all satellite standards (<40 MSps in
32APSK)
LDPC and BCH FEC decoding for C2 and S2 standards
I2C serial bus interfaces (master and host)
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. Si2160C
embeds DiSEqCTM 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).
Fast lock times for all media
Low power consumption
Two power supplies: 1.2 and 3.3 V
The Si2160C offers an on-chip blind scan algorithm for DVB-S/S2/
S2X and DVB-C/C2 standards, as well as a blind lock function.
The Si2160C 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.
