3.2.2.1. Calibration IP

The Calibration IP provides access to the IOPLL and PHY registers through the AXI4-Lite IP interface. You can connect the Calibration IP to up to two periphery interfaces and three PLLs.

You must connect PHY Lite IP instances in different I/O banks to different Calibration IPs.

Connect PHY Lite IP instances in the same I/O bank to the same Calibration IP, but assign different Instance ID in the IP Parameter Editor to differentiate the base address of the instances (Rev B only).
