Zynq: IDELAYCTRL driving REFCLK using PS7 FCLK?

Hi,

 

Are there any problems with driving the REFCLK pin of an IDELAYCTRL from PS7 clocks (200MHz). I am seeing "RDY" being randomly deasserted (device: xc7z020 on Zed board). Is the tolerance level within 10MHz for PS7 clocks?

 

Thanks,

Rejeesh
