ITU G.hn LDPC decoder

TC4400 is a LDPC decoder core that is fully compliant with ITU G.hn (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

Features:

• 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
