1.2.2.2. The GT Transceiver Channel

The GT transceiver channels are used for supporting data rates from 17.4 Gbps to 25.8 Gbps. The PCS Direct datapath that bypasses all PCS blocks is the primary configuration used to support GT data rates from 17.4 Gbps to 25.8 Gbps. Alternatively, the Enhanced PCS in Basic low latency configuration can also be used to support GT data rates from 17.4 Gbps to 25.8 Gbps. The GT transceiver channels can also be configured as GX transceiver channels. When they are configured as GX transceiver channels, the Standard PCS, Enhanced PCS, and PCIe* Gen3 PCS are available and they support data rates from 1.0 Gbps to 17.4 Gbps.
