Si2168-D solutions integrate DVB-T2, DVB-T and DVB-C digital demodulators into a single advanced CMOS technology mixed-signal die for new generation terrestrial and cable TV standards. Leveraging our proven digital demodulation architecture, Si2168-D devices achieve excellent reception performance for each media while significantly minimizing front-end design complexity, cost and power dissipation. Connecting Si2168-D to a terrestrial and cable hybrid TV tuner, such as Si2177 and Si2151 devices, results in a high-performance and cost optimized TV front-end solution.
Si2168-D demodulators accept a standard IF (36 MHz) or low-IF input for terrestrial and cable standards. The main features of the DVB-T2 and T2-Lite modes are 256 QAM with rotated constellations, SISO and MISO support, FEF management, fully autonomous signal acquisition including automatic L1 signaling parsing, scrambling of L1 postsignaling, 600 kHz acquisition range, support for all pilot patterns and DVB-T2/T auto-detection. Si2168-C devices offer an on-chip blind scanning algorithm for DVB-C standard and a blind lock subset mode. The Si2168-C programmable transport stream interface provides a flexible range of output modes and is fully compatible with all MPEG decoders or conditional access modules to support any application.
