Product Information

Back to top
The Si21622C integrates two separate high-performance digital demodulators for the DVB-T2/T, and DVB-C2/C standards into a single compact package. Leveraging Silicon Labs' proven digital demodulation architecture, the Si21622C achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si21622C to a dual terrestrial/cable TV tuner results in a high-performance and cost optimized TV 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 (including T2-Lite) demodulators support all modes specified by the DVB-T2 standard (V1.4.1). Main features of the DVB-T2 mode are, SISO and MISO support, FEF management, fully autonomous signal acquisition including automatic L1 signaling parsing support for all pilot patterns, and DVB-T2/T auto-detection. The DVB-T and DVB-C, including ITU-T J.83 annex B, demodulators are enhanced versions of proven and broadly used Si2164/67/68/69 Silicon Labs devices.

The Si21622C offers an on-chip blind scanning algorithm for the DVB-C, as well as blind lock function. The Si21622C embeds two independent programmable transport stream interfaces which provide a flexible range of out put modes, including a cross-bar functionality, and are fully compatible with all MPEG decoders or conditional access modules to support any customer application.
