Overview

The Si2180 integrates digital demodulators for the Japanese and South American terrestrial ISDB-T standard and for the DVB-T and DVB-C standards in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2180 achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2180 to a hybrid TV tuner or digital only tuner, such as Silicon Labs' Si217x/5x/4x devices, results in a high-performance and cost optimized TV or STB front-end solution.Leveraging significant field experience in DVB terrestrial demodulation (DVB-T), Silicon Labs’ internally-developed ISDB-T 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 J.83 Annex A/C) and the Americas' cable standard (ITU J.83 Annex B).The Si2180 offers an on-chip blind scan algorithm for DVB-C standard, as well as a blind lock function. The Si2180 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.
