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). 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.
