Introduction

The Si2166D integrates digital demodulators for first and second generation satellite DVB standards (DVB-S/S2 and S2X) in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2166D achieves excellent satellite reception performance while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2166D to a satellite silicon 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. Si2166D embeds DiSEqC 2.0 LNB interface for satellite dish control and an equalizer to compensate for echoes in long cable feeds from the antenna to the satellite tuner input. The Si2166D offers an on-chip blind scan algorithm for DVB-S/S2/ S2X standards, as well as a blind lock function. The Si2166D 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.
