Description

The Si2162C integrates digital demodulators for all first and

second generation DVB standards (DVB-T/T2/C/C2) in a single

advanced CMOS die. Leveraging Skyworks' proven digital

demodulation architecture, the Si2162C achieves excellent

reception performance for each media while significantly

minimizing front-end design complexity, cost, and power

dissipation. Connecting the Si2162C 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-T2/T and DVB-C2/C demodulators are next-generation

enhanced versions of proven and broadly-used Skyworks’

Si2169/68/67/66/64/62/60 devices. DVB-T2-Lite (ETSI EN 302

755-V1.3.1) compatibility is also supported.

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 Si2162C offers an on-chip blind scan algorithm for DVB-C/C2

standards, as well as a blind lock function. The Si2162C

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.
