Si2183/82/81/80 Digital ISDB-T TV Demodulators

Si2183/82/81/80 devices integrate digital demodulators for ISDB-T and all first, second and third-generation DVB video broadcasting standards, ISDB-T/DVB-T2/C2/S2X/S2/T/C/S, ISDB-T/DVB-T2/S2X/S2/T/C/S, ISDB-T/DVB S2X/S2/T/C/S and ISDB-T/DVB-T/C respectively, in a single advanced CMOS die. Leveraging our proven digital demodulation architecture, Si2183/82/81/80 demodulators achieve excellent reception performance for each media, while significantly minimizing front-end design complexity, cost and power dissipation. Connecting Si2183/82/81/80 devices to a terrestrial and cable hybrid TV tuner or digital-only tuner, such as Si2177, Si2151, and Si2141, results in a high-performance and cost-optimized TV front-end solution.

Si2183/82/81/80 demodulators can accept a standard IF (36 MHz) or low-IF input for terrestrial and cable standards. The satellite demodulation functionality allows demodulating widespread DVB-S, DIRECTV™ (DSS), DVB-S2 and DIRECTV™ (AMC) legacy standards and Part II of DVB-S2 (S2X) satellite broadcast standard. The main specifications of the new DVB-S2 demodulator are broadcast services, variable coding and modulation (VCM), 8, 16, 32 APSK modulations and code rates and new shorten roll-off factors. A zero-IF interface allows for a seamless connection to market-proven satellite silicon tuners.

Si218x devices offer an on-chip blind scan algorithm for DVB-S2X/S2/S and DVB-C2/C standards and a blind lock function. The Si218x 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 application.
