10G-800G Ethernet MAC and/or PCS/FEC

Support MAC layer, and/or PCS layer and FEC functions with Ethernet rates from 10G to 800G specified by IEEE 802.3 standards.

200G/400G/800G MAC/PCS/FEC

The 200G/400G/800G MAC/PCS/FEC Cores are cutting edge solution to the 200G/400G/800G Ethernet application. The Cores support the Physical Coding Sublayer (PCS) for 64B/66B, type 200G/400G/800GBASE-R function based on the Ethernet Technology Consortium and IEEE 802.3bs.

200G/400G/800G PCS/FEC Features

  • There are 4 PCS Cores: 200GBASE-R only, 400GBASE-R only, 800GBASE-R only and 200G/400G/800GBASE-R combined Core.
  • The PCS layer core supports 64B/66B encoding for transmission of data and control characters, 256/257B transcoding, FEC calculation, and data distribution to support multiple lanes in the Physical Layer. It includes insertion and extraction points for connection to an OTN layer.
  • This core is suitable for use in switch or interface cards or any application that requires a PCS for 200G/400G/800G.
