Description

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 Skyworks' 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 Skyworks' Si217x/5x/4x devices, results in a

high-performance and cost optimized TV or STB front-end

solution.

Skyworks' 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, DVB-C2/C and DVB-S2/S demodulators are nextgeneration

enhanced versions of proven and broadly-used

Skyworks’ Si2169/68/67/66/64/62/60 devices.

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).

The Si2160C offers an on-chip blind scan algorithm for DVBS/

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.
