Description

What are the period jitter specifications for CLKDLL outputs of Virtex-E or Spartan-IIE devices?

I have looked in the "DLL Clock Tolerance, Jitter, and Phase Information" section of the Virtex-E data sheet and in the "DLL Clock Tolerance, Jitter, and Phase Information" section of the Spartan-IIE data sheet, but the information does not appear in either document.

Virtex-E and Spartan-IIE data sheets are available at:
