DVB-S2 demodulator / S2X demodulator

Product code: CMS0014

 
The CMS0014 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 LDPC decoder solution.
The demodulator provides an adaptable starting point for receiver sub-systems to be used in the next-generation of digital TV set-top-boxes, VSAT terminals and related test and monitoring equipment.
