DVB-Satellite demodulator
Product code: CMS0059
The CMS0059 has been designed from the ground-up for high-speed and gate-efficient implementation on FPGA and ASIC platforms and offers "near Shannon limit" performance when combined with an advanced FEC decoder solution.
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.
The core may be seamlessly linked to the Commsonic CMS0077 FEC Decoder for a complete satellite receiver solution.
