The Creonic DVB-S2X wideband modulator is a low-complexity high-performance solution that allows for symbol rates of up to 500 MSymb/s (4 Gbit/s for 256-APSK) on state-of-the-art FPGAs. The IP core performs all tasks of the inner transmitter and complements the Creonic DVB-S2X wideband receiver solutions (DVB-S2X wideband demodulator and DVB-S2X LDPC/BCH wideband decoder). The modulator expects BBFrames after mode adaptation as input and performs stream adaptation, FEC encoding, mapping, PL framing and modulation.
