Si21802-B60 Dual ISDB-T and DVB-T/C Demodulator Description The Si21802 integrates two separate high-performance digital demodulators for the Japanese and South American terrestrial ISDB-T standard and for the DVB-T and DVB-C standards in a single compact package. Leveraging Silicon Labs' proven digital demodulation architecture, the Si21802 achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si21802 to a dual terrestrial/cable TV tuner results in a high-performance and cost optimized TV or STB front-end solution. Leveraging significant field experience in DVB terrestrial demodulation (DVB-T), the Si21802 dual demodulator can accept standard or low-IF inputs (differential) and complies with the Brazilian SBTVD-T terrestrial specifications (ABNT NBR 16.601 and 15.604). Main features include fast channel scan, very short lock times, state of the art CCI performance, partial reception, and auxiliary channels decoding. DVB-T and DVB-C demodulators are next-generation enhanced versions of proven and broadly-used Silicon Labs’ Si2169/68/67/66/64/62/60 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 Si21802 offers an on-chip blind scanning algorithm for DVB-C standard, as well as blind lock function. The Si21802 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.
