Standard PCS Interface Ports
Figure 14–6 illustrates the Standard PCI Interfaces. If you enable both the Standard
PCS and 10G PCS your top-level HDL file includes all the interfaces for both.
Table 14–33 describes the ports available for the Standard PCS interface. When you
enable both the Standard and 10G datapaths, both sets of signals are included in the
top-level HDL file for the Native PHY.
1 In Table 14–33, the column labeled “Synchronous to tx_std_coreclkin/rx_std_coreclkin”
applies when the phase compensation FIFO is not in register mode.

Description
Clocks
tx_std_clkout[<n>-1:0]
Output —
TX Parallel clock output as shown in the The Standard
PCS Datapath figure.
rx_std_clkout[<n>-1:0]
Output —
RX parallel clock output as shown in The Standard
PCS Datapath figure. The CDR circuitry recovers RX
parallel clock from the RX data stream.
tx_std_coreclkin[<n>-1:0]
Input —
TX parallel clock input from the FPGA fabric that
drives the write side of the TX phase compensation
FIFO as shown in The Standard PCS Datapath figure.
rx_std_coreclkin[<n>-1:0]
Input —
RX parallel clock that drives the read side of the RX
phase compensation FIFO The Standard PCS
Datapath figure.
