ns
Notes:
1.
IFF = Input Flip-Flop or Latch
2.
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.
3.
DLL output jitter is already included in the timing calculation.
4.
A zero hold time listing indicates no hold time or a negative hold time.
5.
For data input with different standards, adjust the setup time delay by the values shown in "IOB Input Delay Adjustments for Different
Standards," page 57. For a global clock input with standards other than LVTTL, adjust delays with values from the "I/O Standard
