The Stratix IV GX and GT transceiver provides the Enable low latency PCS mode
option in the ALTGX MegaWizard
8B/10B encoder in the datapath is disabled.
TX Phase Compensation FIFO
The TX phase compensation FIFO interfaces the transmitter channel PCS and the
FPGA fabric PCIe interface. It compensates for the phase difference between the
low-speed parallel clock and the FPGA fabric interface clock. The TX phase
compensation FIFO operates in low-latency and high-latency modes.
