Product Information

Back to top
The Si21682D integrates two separate high-performance digital demodulators for the DVB-T2/T and DVB-C standards into a single compact package. Leveraging Silicon Labs' proven digital demodulation architecture, the Si21682D achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si21682D to a dual terrestrial/cable TV tuner results in a high-performance and cost optimized TV front-end solution.

Silicon Labs’ internally-developed 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 Si21682D offers an on-chip blind scanning algorithm for the DVB-C standard, as well as blind lock function. The Si21682D embeds two independent programmable transport stream interfaces which provide a flexible range of output modes, including a cross-bar functionality, and are fully compatible with all MPEG decoders or conditional access modules to support any customer application.
