DVB-S demodulator / DSNG demodulator

Product code: CMS0048

The CMS0048 has been designed from the ground-up for high-speed and gate-efficient implementation on FPGA and ASIC platforms and offers very high performance when combined with either the integrated FEC decoder or an external advanced FEC decoder.
The demodulator provides an adaptable starting point for receiver sub-systems to be used in both the current and next-generation of digital TV set-top-boxes, VSAT terminals and related test and monitoring equipment.
