    ITU LDPC decoder

    Product code: TC4400

    TC4400 is a LDPC decoder core that is fully compliant with ITU (wireline home networking) specifications. It support a decoded throughput up to 1 Gbits/s on high end process nodes. The core is available for ASIC and FPGA devices.

    An optional support of the HomeplugAV specifications is provided using a versatile turbo/LDPC architecture (TC4410)

    The corresponding LDPC encoder is also available.

    Functional coverage:

    • repetition handling
    • block size: 168 to 4320 payload bits
    • code rates covered: 1/2, 2/3, 3/4, 5/6, 16/18, 20/21


    • decoded bitrate up to 1 Gbps
    • repetition handling (buffer and interfacing)
    • iteration stopping feature
    • channel BER estimator
    • frame-by-frame programmability of code rate, block size, number of iterations
    • ASIC delivery: Verilog or VHDL RTL code
    • Single FPGA Core (no external memory required), available on all popular Xilinx, Altera and Lattice devices
