The Si2169D integrates digital demodulators for first and second generation DVB standards (DVB-T2/T/C/S/S2 and S2X) in a single advanced CMOS die. Leveraging Skyworks' proven digital demodulation architecture, the Si2169D achieves excellent reception performance for each media while significantly minimizing front-end design complexity, cost, and power dissipation. Connecting the Si2169D to a hybrid TV tuner or digital only tuner, such as Skyworks' Si217x/5x/4x devices, results in a high-performance and cost optimized TV or STB front-end solution. Skyworks internally developed DVB-T2, including T2-Lite, demodulator can accept a standard IF (36 MHz) or low-IF input and support all modes specified by the DVB-T2 standard.
Main features of the DVB-T2 mode are 256 QAM with rotated constellations, SISO and MISO support, FEF management, fully autonomous signal acquisition including automatic L1 signaling parsing, 600 kHz acquisition range, support for all pilot patterns, and DVB-T2/T auto-detection. DVB-T, DVB-C, and DVB-S2/S demodulators are next-generation enhanced versions of proven and broadly-used Skyworks’ Si2169/68/67/66/64/62/60 devices.
