High-performance digital demodulator into single compact package

安富利:
The Si21692 integrates two separate high-performance DVB-T2, DVB-T, DVB-C, DVB-S, and DVB-S2 digital demodulators into a single compact package for terrestrial, cable, and satellite TV standards. 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 to both a dual terrestrial/cable TV tuner, and a dual satellite 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 V1.3.1. 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 widely deployed DVB-S, DIRECTV™ DSS legacy standards, and new generation DVB-S2 AMC compliant satellite broadcasts. A zero-IF interface allows for a seamless connection to market proven satellite silicon tuners. The Si21692 offers an on-chip blind scanning algorithm for DVB-S/S2 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 inputThe Si21692 embeds two independent programmable transport stream interfaces which provide a flexible range of output modes and are fully compatible with all MPEG decoders or conditional access modules to support any customer application
