Hi,

The dev kit uses the pins that you show in the screenshot for CXL interface (which is based on PCIe) and uses the HCSL IO standard which is nearer to the LVPECL interface.

However, if you use this F-tile for some other interface, recommend you to follow the datasheet and assign LVDS.

The decision should be based on the data rate, interface recommendation and power consumption. There are many references on internet to each of the type of interface.
