This is a DVB-S2X Modulator IP core with an integrated LDPC encoder has been designed specifically to address the requirements of the ETSI DVB-S2X forward-link satellite standard (EN 302 307), section-1 together with the section-2 extensions (DVB-S2X). The core can operate in CCM and VCM/ACM modes. This core provides all the necessary processing steps to modulate a single transport stream (or baseband frame) into a complex I/Q signal for input to pair DACs or an interpolating DAC device such as the AD9857(or AD9957). Optionally, the output can be selected as an IF to supply a signal DAC.
