Product Information

Back to top
The Si21662D integrates two separate high-performance digital demodulators for the DVB-S2/S and DVB-S2X standards into a single compact package. Leveraging Silicon Labs' proven digital demodulation architecture, the Si21662D achieves excellent reception performance while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si21662D to a dual satellite tuner, results in a high-performance and cost optimized TV or STB front-end solution.

The satellite reception allows demodulating widespread DVB-S, DIRECTV™ (DSS), DVB-S2, DIRECTV™ (AMC) legacy standards, and new Part II of DVB-S2 (S2X) satellite broadcast standard. A zero-IF interface (differential) allows for a seamless connection to market proven satellite silicon tuners. It also integrates two DiSEqC™ 2.0 LNB interfaces for satellite dish control and, for each satellite demodulator, an equalizer to compensate for echoes in long cable feeds from the LNB to the satellite tuner RF input.

Variable Coding and Modulation (VCM), QPSK/8PSK, 8/16/32APSK demodulation schemes and broadcast services profile are the main specifications of the DVB-S2/S2X demodulator. Silicon Labs' innovative LDPC and BCH decoding architecture delivers best-in-class reception while exhibiting low power dissipation.

The Si21662D offers an on-chip blind scanning algorithm, as well as blind lock function.

The Si21662D 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.
