I have a board with XCKU115-2FLVB2104I. I need to drive a DAC with this FPGA the DAC frequency that I need is 750MHz. I was wondering if it is possible to generate and deliver 750MHz clock out of GTH through gtrefclko or gtrefclk1. If this is not possible can you please tell me what the max frequency I can go up to is. Thank you.

From the datasheet, you don't even need the GTH - you can drive 1600Mbps (ie sufficient for an 800MHz clock signal) through a regular HP I/O port in native LVDS mode.
