Signal Name Direction Description
pll_ref_clk
Input Reference clock for the PHY PLLs. The
frequency range is 60–700 MHz.
Optional Reset Control and Status Interface
The following table describes the signals in the optional reset control and status interface. These signals
are available if you do not enable the embedded reset controller. For more information including timing
diagrams, refer to Transceiver Reset Control in Stratix V Devices in volume 2 of the Stratix V Device
Handbook.

Signal Name Direction Description
pll_powerdown
Input When asserted, resets the TX PLL.
tx_digitalreset[<n>-1:0]
Input When asserted, reset all blocks in the TX PCS. If
your design includes bonded TX PCS channels,
refer to Timing Constraints for Reset Signals when
Using Bonded PCS Channels for a SDC
constraint you must include in your design.
tx_analogreset[<n>-1:0]
Input When asserted, resets all blocks in the TX PMA.
tx_cal_busy[<n>-1:0]
Output When asserted, indicates that the initial TX
calibration is in progress. It is also asserted if
reconfiguration controller is reset. It will not be
asserted if you manually re-trigger the calibration
IP. You must hold the channel in reset until
calibration completes.
rx_digitalreset[<n>-1:0]
Input When asserted, resets the RX PCS.
rx_analogreset[<n>-1:0]
Input When asserted, resets the RX CDR.
rx_cal_busy[<n>-1:0]
Output When asserted, indicates that the initial RX
calibration is in progress. It is also asserted if
reconfiguration controller is reset. It will not be
asserted if you manually re-trigger the calibration
IP.
