The DVB-S/-DSNG Modulator with integrated Reed-Solomon encoder has been designed specifically to address the requirements of the ETSI DVB-S forward-link satellite standard (EN 300 421), with further options available for compatibility with the ETSI DVB-DSNG digital satellite news gathering standard (EN 301 210). The core provides all the necessary processing steps to modulate a single transport stream into a complex I/Q signal for input to a pair of DACs, or an interpolating DAC device. Optionally, the output can be selected as an IF to supply a signal DAC. The active FEC code-rate is controlled via a control register. The design has been optimized to provide excellent performance in FPGA devices.
