Product Summary

The Si2169 integrates DVB-T2, DVB-T, DVB-C, DVB-S, andDVB-S2 digital demodulators into a single advanced CMOStechnology mixed-signal die for next generation terrestrial,cable, and satellite TV standards. Leveraging Silicon Labs'proven digital demodulation architecture, the Si2169achieves excellent reception performance for each mediawhile significantly minimizing front-end design complexity,cost, and power dissipation. Connecting the Si2169 to aterrestrial and cable hybrid TV tuner or digital only tuner,such as Silicon Labs’ Si2176/56/46 devices, results in ahigh-performance and cost optimized TV front-end solution.Silicon Labs internally developed DVB-T2 demodulator canaccept a standard IF (36 MHz) or low-IF input and supportall modes specified by the DVB-T2 standard. Main featuresof the DVB-T2 mode are 256 QAM with rotatedconstellations, SISO and MISO support, FEF management,fully autonomous signal acquisition including automatic L1signalling parsing, 600 kHz acquisition range, support for allpilot patterns, and DVB-T2/T auto-detection. The DVB-T andDVB-C demodulators are enhanced versions of proven andbroadly used Si2161/63/65/67 Silicon Labs devices
