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. In addition, the core can perform baseband interpolation and output gain adjustment. The output of the core is designed to be followed by a DAC and RF front end.
