Guidelines for DPA-Disabled Differential Channels
When you use DPA-disabled channels, you must adhere to the guidelines in the
following sections.
DPA-Disabled Channel Driving Distance
Each PLL can drive all the DPA-disabled channels in the entire bank.
Using Corner and Center PLLs in Arria II GX Devices
You can use a corner PLL to drive all transmitter channels and you can use a center
PLL to drive all DPA-disabled receiver channels in the same I/O bank. In other
words, you can drive a transmitter channel and a receiver channel in the same LAB
row by two different PLLs, as shown in
