12.3. PCS, OTN, and FlexE Modes

Each GTS Ethernet Hard IP instance contains a full featured multi-channel PCS layer, which offers a number of interfacing options from the FPGA fabric.

The IP offers the following PCS options:

  • PCS—This mode uses the MII interface to transmit and receive Ethernet packets for data rate of 10GE . It consists of:
    • PCS—Direct Single Channel with and without FEC
    • PCS—Direct Multiple Channel with and without FEC
  • OTN and FlexE—This mode uses the PCS66 interface to read and write 66 bit blocks data, from and to the PMA block.
