DVB-T2/C2/T/C Digital TV Demodulator
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 Silicon Labs' 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 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 and DVB-C2/C 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 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.
