Part Number : DVB-S2X-Decoder
Short Desc. : DVB-S2X LDPC/BCH Decoder
Overview :

DVB-S2X is the next generation satellite transmission standard that extends 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. 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.

Features : - Compliant with ETSI 302 307 V1.2.1 (2009-08) (DVB-S2) and 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

- 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, Altera).
