11.11. Low Latency PHY Clock Interface
The following table describes reference clock for the Low Latency PHY. The input reference clock, pll_ref_clk, drives a PLL inside the PHY-layer block, and a PLL output clock, rx_clkout is used for all data, command, and status inputs and outputs.

Description |
---|---|---|
tx_coreclkin[<n>-1:0] |
Input |
This is an optional clock to drive the write side of the TX FIFO. |
rx_coreclkin[<n>-1:0] |
Input |
This is an optional clock to drive the read side of the RX FIFO. |
pll_ref_clk |
Input |
Reference clock for the PHY PLLs. The frequency range is 60–700 MHz. |
