the new tuner is based on Si21692/682-D from SILABS silicon
Si21692/682-D Dual Digital TV Demodulators

Each of the Si21692/682-D dual demodulators integrate two separate high-performance single demodulators in a compact 8 x 8 mm QFN package. The Si21692/682-D support DVB-T2/S2X/S2/T/C/S and DVB-T2/T/C, respectively. Leveraging Silicon Labs' proven digital demodulation architecture, each embedded demodulator achieves excellent reception performance for each media while significantly minimizing front-end design complexity and cost. Connecting the Si21692/682-D to both a dual terrestrial/cable TV tuner, and a dual satellite tuner, results in a high-performance and cost optimized dual-channel TV or STB front-end solution.

Silicon Labs’ internally-developed DVB-T2 (including T2-Lite) demodulators support all modes specified by the DVB-T2 standard (V1.3.1). 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 demodulators are enhanced versions of proven and broadly used Si2167/68/69 Silicon Labs devices. The satellite demodulation functionality allows demodulating widespread DVB-S, DIRECTV™ (DSS), DVB-S2 and DIRECTV™ (AMC) legacy standards, as well as new Part II of DVB-S2 (S2X) satellite broadcast standard. A zero-IF interface allows for a seamless connection to market proven satellite silicon tuners.

The Si216x2 offers an on-chip blind scanning algorithm for DVB-S2X/S2/S and DVB-C standards (as well as blind lock). 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.

The Si216x2 embeds two independent programmable transport stream interfaces which provide a flexible range of output modes, including a TS cross-bar functionality, and are fully compatible with all MPEG decoders or conditional access modules to support any customer application.
