Table 18. Arria V and Stratix V Transceiver Native PHY (TX) Common Interface PortsThis table describes the Arria V and Stratix V Transceiver Native PHY (TX) common interface ports.
Signals	Direction	Description
Clocks
`tx_pll_refclk`	Input	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
`pll_powerdown`	Input	When asserted, resets the TX PLL. Connect to the Transceiver PHY Reset Controller (TX) IP core.
`pll_locked`	Output	When asserted, indicates that the TX PLL is locked. Connect to the Transceiver PHY Reset Controller (TX) IP core.
PCS Ports
`unused_tx_parallel_data`	Input	Leave unconnected.
`tx_parallel_data[S410-1:0]`	Input	PCS TX parallel data. Note: S=Symbols per clock.
PMA Port
`tx_serial_data[3:0]`	Output	TX differential serial output data.
Calibration Status Port
`tx_cal_busy[3:0]`	Output	When asserted, indicates that the initial TX calibration is in progress. This port is also asserted if the reconfiguration controller is reset. Connect to the Transceiver PHY Reset Controller (TX) IP core.
Reconfiguration Ports
`reconfig_to_xcvr[349:0]`	Input	Reconfiguration signals from the Transceiver Reconfiguration Controller.
`reconfig_from_xcvr[229:0]`	Output	Reconfiguration signals to the Transceiver Reconfiguration Controller.
