​Si2164/62/60-C Digital DVB-C2 TV Demodulators 

The Si2164/62/60-C integrates digital demodulators for all of the first and second generation DVB video broadcasting standards, DVB-T2/C2/S2X/S2/T/C/S, DVB-T2/C2/T/C and DVB-C2/S2X/S2/T/C/S respectively, in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2164/62/60-C achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost and power dissipation.

Connecting the Si2164/62/60-C to a terrestrial and cable hybrid TV tuner or digital only tuner, such as Silicon Labs' Si2177 and Si2151/41 devices, results in a high-performance and cost optimized TV front-end solution.

Silicon Labs' internally developed DVB-C2 demodulators 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. The DVB-T2/T, DVB-S2X/S2 and DVB-C demodulator IP blocks are enhanced versions of the 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.

The satellite demodulation functionality allows demodulating widely deployed DVB-S, DVB-S2 (AMC compliant), DIRECTVTM (DSS) legacy standards, and new generation DVB-S2X (DVB-S2 Extensions) satellite broadcasts. A zero-IF interface (differential) allows for a seamless connection to market proven satellite silicon tuners. Si216x embeds DiSEqCTM 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-T J.83 Annex B).

The Si216x offers an on-chip blind scan algorithm for DVB-S2/S2X and DVB-C/C2 standards, as well as a blind lock function. The Si216x 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.
