Virtex-II - Where are the global clock input adjustment values? (i.e.,Tgplvttl, Tgplvds, etc.)

Description

In the Virtex-E data sheet, there is a table for the global clock input adjustment based on the I/O standard. However, this information is not available in the Virtex-II data sheet. Where can I find these values?

Solution

In Virtex-II, there is no need for special adjustments on the global clock inputs. The global clock inputs in Virtex-II devices are the same as in any other I/Os. 

 

The I/O input adjustment is available in the "Virtex-II Complete Data Sheet (All four modules)" Data Sheet", (DS031):
