The Creonic CCSDS LDPC IP cores support the LDPC coding scheme as defined by the CCSDS standard. The LDPC code with single rate 223/255 was specifically designed for Near-Earth missions, but the excellent error correction performance also makes it an ideal solution for a wide variety of high-throughput applications.

Key benefits of the decoder:
- Gains of up to 3 dB compared to Viterbi decoders
- Low-power and low-complexity design
- Layered LDPC decoder architecture, for convergence behavior that is twice as fast as non-layered LDPC decoders
- 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 statistic information (number of iterations, decoding success) Collection of statistic information (number of iterations, decoding success)
