The Creonic DVB-S2X decoder is a scalable solution that allows for symbol rates of up to 100 MSymb/s on state-of-the-art FPGAs. 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.
Applications
  • Satellite communication (Digital Video Broadcasting, Interactive Services, News Gathering, Professional Services)
  • Nanosatellite and CubeSat devices
  • Applications with the highest demands on forward error correction
  • Applications with the need for a wide range of code rates
 
Standard Features the Core Supports
  • Compliant with ETSI EN 302 307-1 V1.4.1 (2014-11) (DVB-S2) and ETSI EN 302 307-2 V1.1.1 (2014-10) (DVB-S2X).
  • Supports ACM, CCM, and VCM modes.
  • Support for short, medium and long blocks (16200, 32400 and 64800 bits).
  • Support for all modulation schemes (BPSK, QPSK, 8-PSK, 16-APSK, 32-APSK, 64-APSK, 128-APSK, 256-APSK).
  • Support for very low SNR modes (VLSNR) with SNRs below -9 dB.
  • Support for all LDPC and BCH codes as defined by the standard.
 
Your Benefits
  • Validated against 3rd party DVB-S2X modulators.
  • Based on industry-proven design for DVB-S2.
  • Decoder contains soft-decision demapper, block deinterleaver, LDPC decoder, BCH decoder, and descrambler.
  • Low-power and low-complexity design.
  • Burst-to-burst on-the-fly configuration.
  • Faster convergence due to layered LDPC decoder architecture.
  • Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy.
  • Configurable amount of LDPC decoding iterations for trading-off throughput and error correction performance.
  • Collection of statistics (decoding success indicator, average number of iterations).
  • Available for ASIC and FPGAs (Xilinx, Intel, Microchip).
  • Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model.
