Is it necessary to use a jitter attenuator chip on the PCI clock? I am using a Kintex 7 part. I see that some boards have them and other dont. I have the schematics for the KC705 and it doesnt use one.

If the clock source jitter is with in GT reference clock specifications, no need to have jitter attenuator
You can find the specfications of phase noise for 7 series in below link
For UltraScale you can find the details in device datasheet.
Hope this helps
