M88CS2200  -  MPEG-2 Decoder SoC with DVB-S Demodulator

The M88CS2200 is a cost-effective DVB-S SoC (system-on-chip) device that integrates LNB controller, DVB-S demodulator and MPEG-2 A/V decoder in a compact package. The device is fully compliant with DVB-S specification and supports PAL and NTSC television formats. It receives baseband signals from an external tuner, digitally demodulates the signals to recover MPEG-2 transport stream, and then implements real-time PID filtering, A/V decoding and TV encoding to produce analog CVBS, S-video, YPbPr or RGB video and L/R-channel audio. The device also supports digital SPDIF audio output, VBI data insertion and DVB compliant subtitle display. It really offers a flexible front-to-back-end solution for the satellite digital TV markets.
