LDPC Encoder/Decoder
DOCSIS 3.1 LDPC Decoder IP-Cores (PLC / NCP / Data)
Data Over Cable Service Interface Specification (DOCSIS) is an international telecommunications standard that permits the addition of high-bandwidth data transfer to an existing cable TV (CATV) system. It is employed by many cable television operators to provide Internet access over their existing hybrid fiber-coaxial infrastructure.
The Creonic DOCSIS 3.1 LDPC decoders are a complete solution for the downstream forward error correction, i.e. PLC decoder, NCP decoder and data decoder are included.
Applications
- Cable TV networks
- Wired transmission with the highest demands on forward error correction
Features the PLC Decoder Core Supports
- Soft-Decision Demapper, Derandomizer, Deinterleaver, Depuncturer, and LDPC Decoder are included.
- Support for 4k and 8K FFT sizes
- Support for 16-QAM modulation
Features the NCP Decoder Core Supports
- Soft-Decision Demapper, Derandomizer, Deinterleaver, Depuncturer, Deshortener, and LDPC Decoder are included.
- Support for 4k and 8K FFT sizes
- Support for QPSK, 16-QAM, and 64-QAM modulations
- Provides derandomization data for downstream data path
Features the Data Decoder Core Supports
- Zero-bit Insertion, Parity Deinterleaver, LDPC Decoder, Shortener, and BCH Decoder are included.
- Support for all block sizes, incl. shortening (3 to 1779 bytes)
- Data rate of more than 2.3 Gbit/s
Your Benefits
- Low-power and low-complexity design.
- Frame-to-frame on-the-fly configuration.
- Faster convergence due to layered LDPC decoder architectures.
- 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, modified bits).
- Available for ASIC and FPGAs (Xilinx, Intel).
- Deliverable includes VHDL source code or synthesized netlist, VHDL testbench, and bit-accurate Matlab, C or C++ simulation model.
