TC4400: ITU-Ghn LDPC encoder/decoder Cores
The TC4400 Core is a LDPC decoder Core that is fully compliant with ITU-Ghn (wireline home networking) specifications. The Core is available for ASIC and FPGA devices. An optional support of the HomeplugAV specifications is provided using a versatile turbo/LDPC architecture. The corresponding LDPC encoder is also available.
Decoder Core features:
- 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
