Chapter 6: XAUI PHY IP Core 6–5
Analog Parameters
November 2012 Altera Corporation Altera Transceiver PHY IP Core
User Guide
Example 6–1 shows how to remove the restriction on logical lane 0 channel
assignment in Stratix V devices by redefining the
pma_bonding_master
parameter
using the Quartus II Assignment Editor. In this example, the
pma_bonding_master
was
originally assigned to physical channel 1. (The original assignment could also have
been to physical channel 4.) The
to
parameter reassigns the
pma_bonding_master
to
the XAUI instance name shown in quotation marks. You must substitute the instance
name from your design for the instance name shown in quotation marks

Base data rate
1 × Lane rate
2 × Lane rate
4 × Lane rate
The base data rate is the frequency of the clock input to the PLL.
Select a base data rate that minimizes the number of PLLs required
to generate all the clock s required for data transmission. By
selecting an appropriate base data rate, you can change data rates
by changing the divider used by the clock generation block. This
parameter is available for Stratix V devices.
Number of XAUI interfaces 1
Specifies the number of XAUI interfaces. Only 1 is available in the
current release.
