The reference clock input to the TX PLL.

tx_std_clkout[3:0] Output

TX parallel clock output.
tx_std_coreclkin[3:0] Input

TX parallel clock that drives the write side of the TX phase compensation FIFO.

Connect to tx_std_clkout[0] ports.

Resets
tx_analogreset[3:0] Input

When asserted, resets all the blocks in TX PMA.

Connect to Transceiver PHY Reset Controller (TX) IP core.
tx_digitalreset[3:0] Input

When asserted, resets all the blocks in TX PCS.

Connect to the Transceiver PHY Reset Controller (TX) IP core.
TX PLL
