Zynq US+ GTH Reference clock rise/fall time

Jump to solution

Hello,

In the DS925 for the GTH Reference clock rise/fall time (Table 101) only a typical value is specified. Could someone from Xilinx give me the max value, please?

Thanks

There is no specified maximum.  A compliant LVDS or LVPECL input should be fine.  The main thing is to meet the phase noise mask and slow transition times could make that more difficult.

Hi,

 

Does this "no specified maximum" also apply to the Kintex Ultrascale GTH Transceivers?  (DS892 (v1.18) May 21 2019, Table 53, Page 51).

 

Thanks,

Max
