DVB-S2X Modulator 

The Creonic DVB-S2X modulator is a low-complexity high-performance solution that allows for symbol rates of up to 250 MSymb/s (2 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 receiver solutions (DVB-S2X demodulator and DVB-S2X LDPC/BCH decoder). Additionally, the core comes with a license option for the Creonic DVB-CID modulator.

DVB-S2X is the next generation satellite transmission standard which is an extended version of its well-established predecessor DVB-S2. The new specification allows for spectral efficiency gains of up to 50% by offering lower roll-off factors, higher modulations and a finer code rate granularity compared to DVB-S2.
