Board Component Descriptions
• Four GTY transceivers (bank 227) are wired to PCIe edge connector CN1 lanes 3:0.
The GTY transceivers in the XCVU9P-L2FSGD2104E are grouped into four channels or quads.
The reference clock for a quad can be sourced from the quad above or the quad below the
GTY quad of interest. The six GTY quads used on the VCU1525 board have the following
connectivity (also see
