Description
Clock Inputs and Output Signals
tx_pll_refclk[
Input
The reference clock input to the TX PLL.
tx_pma_clkout[
Output
TX parallel clock output from PMA
rx_pma_clkout[
Output
RX parallel clock (recovered clock) output
from PMA
rx_cdr_refclk[
Input
Input reference clock for the RX PFD
circuit.
ext_pll_clk[
-1:0]
Input
This optional signal is created when you
select the Use external TX PLL option. If
you instantiate a fractional PLL which is
external to the Native PHY IP, then connect
the output clock of this PLL to
ext_pll_
clk
.
