Si2168-D60 DVB-T2/T/C Digital TV Demodulator Description Features The Si2168D integrates digital demodulators for first and second generation DVB standards (DVB-T2/T/C) in a single advanced CMOS die. Leveraging Silicon Labs' proven digital demodulation architecture, the Si2168D achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2168D 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. - Pin-to-pin compatible with all Si216x/8x single demods family - API compatible with all single and dual demods families - DVB-T2 (ETSI EN 302 755-V1.4.1) with T2-Lite (Annex I) - Bandwidth: 1.7, 5, 6, 7, and 8 MHz (and extended BW) - NorDig Unified 2.5 and D-Book 8 compliant - DVB-T (ETSI EN 300 744) - OFDM demodulator and enhanced FEC decoder - NorDig Unified 2.5 and D-Book 8 compliant - DVB-C (ETSI EN 300 429) and ITU-T J.83 Annex A/B/C - QAM demodulator and FEC decoder - 1 to 7.2 MSymbol/s - I2C serial bus interfaces (master and host) - Firmware control (embedded ROM/NVM) - Upgradeable with patch download via I2C or fast SPI - Flexible TS output interface (serial, parallel, and slave) - Fast lock times for all media - Low power consumption - Two power supplies: 1.2 and 3.3 V - 7x7 mm, QFN-48 pin package, Pb-free/RoHS compliant DVB-T and DVB-C demodulators are next-generation enhanced versions of proven and broadly-used Silicon Labs’ Si2169/68/67/ 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 Si2168D offers an on-chip blind scan algorithm for the DVB-C standard, as well as a blind lock function. The Si2168D 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.
