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.
For data input with different standards, adjust the setup time delay by the values shown in
Standards, page
Global Clock Input Adjustments, page
A zero hold time listing indicates no hold time or a negative hold time.
