Product Information

Back to top
The Si2168D integrates digital demodulators for first and second generation DVB standards (DVB-T2/T/C) in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2168D achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2168D 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-T2, including T2-Lite, demodulator can accept a standard IF (36 MHz) or low-IF input and support all modes specified by the DVB-T2 standard. Main features of the DVB-T2 mode are 256 QAM with rotated constellations, SISO and MISO support, FEF management, fully autonomous signal acquisition including automatic L1 signaling parsing, 600 kHz acquisition range, support for all pilot patterns, and DVB-T2/T auto-detection.

DVB-T and DVB-C demodulators are next-generation enhanced versions of proven and broadly-used Silicon Labs’ Si2169/68/67/64/62/60 devices.

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 Si2168D offers an on-chip blind scan algorithm for the DVB-C standard, as well as a blind lock function. The Si2168D 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.

Symmetry Electronics is an authorized Silicon Labs distributor.
