Virtex-E Pin-to-Pin Input Parameter Guidelines
All devices are 100% functionally tested. Listed below are representative values for typical pin locations and normal clock
loading. Values are expressed in nanoseconds unless otherwise noted.

Input Setup and Hold Time Relative to Global Clock Input Signal
for LVTTL Standard.
For data input with different standards, adjust the setup time
delay by the values shown in

Global Clock and IFF, without DLL
IFF = Input Flip-Flop or Latch
Setup time is measured relative to the Global Clock input signal with the fastest route and the lightest load. Hold time is measured
relative to the Global Clock input signal with the slowest route and heaviest load.
DLL output jitter is already included in the timing calculation.
IFF = Input Flip-Flop or Latch
Setup time is measured relative to the Global Clock input signal with the fastest route and the lightest load. Hold time is measured
relative to the Global Clock input signal with the slowest route and heaviest load.
A Zero “0” Hold Time listing indicates no hold time or a negative hold time. Negative values can not be guaranteed “best-case”, but
if a “0” is listed, there is no positive hold time.
