2.3 Gbit/s DOCSIS 3.1 Downstream LDPC Decoder (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 downstream LDPC Decoders cover PLC, NCP and Data decoding of DOCSIS 3.1.

特色

Data decoder includes Zero-bit Insertion, Parity Deinterleaver, LDPC Decoder, Shortener, and BCH Decoder.
Data decoder supports all block sizes, incl. shortening (3 to 1779 bytes).

优势

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).
