Table 14-38: Native PHY Common Interfaces
Name Direction Description
Clock Inputs and Output Signals
tx_pll_refclk
[ -1:0]
Input The reference clock input to the TX PLL.
tx_pma_clkout
[ -1:0]
Output TX parallel clock output from PMA
rx_pma_clkout
[ -1:0]
Output RX parallel clock (recovered clock) output from
PMA
rx_cdr_refclk
[ -1:0]
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
.
