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)
