ITU-Ghn LDPC Encoder / 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 (see TC4410)

• bit-LLR input interface
• repetition handling (buffer and interfacing)
• decoded bitrate up to 1 Gbps (Ghn mode) and 600 Mbps (HomeplugAV mode)
• iteration stopping feature
• block size : 168 to 4320 payload bits
• code rates covered: 1/2, 2/3, 3/4, 5/6, 16/18, 20/21
• optional Homeplug-AV turbo decoder
• Frame-by-frame programmability of code rate and size
• ASIC delivery : Verilog or VHDL RTL code.
• Single FPGA Core (no external memory required), available on all popular Xilinx, Altera and Lattice devices
