DVB-Satellite FEC Decoder

Product code: CMS0077

The Commsonic CMS0077 Satellite FEC Decoder has been designed specifically to meet the requirements of the DVB-S2, DVB-S2X and ISDB-S3 advanced wide-band digital satellite standards.
The core integrates seamlessly with the Commsonic CMS0059 DVB-S2 / DVB-S2X / ISDB-S3 physical layer demodulator core to provide a complete satellite decoding solution.
The core provides all the necessary processing steps to convert a demodulated complex I/Q signal into a standard TS output stream. If configured for ACM operation, the FEC mode can dynamically change on a frame-by-frame basis.
