12–32 Chapter 12: Stratix V Transceiver Native PHY IP Core
Common Interface Ports
Altera Transceiver PHY IP Core November 2012 Altera Corporation
User Guide
The port descriptions use the following variables to represent parameters:
<n>—The number of lanes
<p>—The number of PLLs
<r>—the number of CDR references clocks selected
Common Interface Ports
Common interface consists of reset, clock signals, serial interface ports, control and
status ports, parallel data ports, PMA ports, QPI ports, and reconfig interface ports.
Figure 12–5 illustrates these ports.
Table 12–31 describes these ports.

Name Direction Description
Clock Inputs and Output Signals
tx_pll_refclk[<r>-1:0]
Input The reference clock input to the TX PLL.
tx_pma_clkout[<n>-1:0]
Output TX parallel clock output from PMA
rx_pma_clkout[<n>-1:0]
Output RX parallel clock (recovered clock) output from PMA
rx_clklow[<n>-1:0]
Output
The RX recovered clock. You can use this clock as an input to an
external PPM detector.
rx_fref[<n>-1:0]
Output
RX phase frequency detector (PFD) reference clock. You can use
this clock as an input to an external PPM detector.
