Figure 1-18: GT Transceiver Channel in Full Duplex Mode Operating Between 17.4 Gbps and 28.3 Gbps
Notes:
(3) The Standard PCS and PCIe Gen3 PCS blocks are available when the GT channel is configured as a GX transceiver channel.
(1) The Enhanced PCS must be configured in Basic low latency mode to support data rate range from 17.4 Gbps to 28.3 Gbps.
(2) The FPGA Fabric - PCS and PCS-PMA interface widths are configurable.
