Hello,
we use artix7-50T, can the rate of different channels in the same GTP Quad be different? must is be the same?
Thank you!

Looking at UG482 fig 2-4 there are only 2 PLLs availabale in a GTP Quad, so you cannot run all 4 channels at a different rates, but you can run at 2 different rates where you can configure each channel to opeate from either of the 2 PLLs where each PLL can also be fed from a unique reference clock.

Yes, you can use the dynamic reconfiguration port to change the PLL settings.
