Setup Times
Hold Times
The numbers in this table are tested using the methodology presented in
Table 7
This setup time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or the data
Input. If this is true of the Global Clock Input, subtract the appropriate adjustment from
appropriate Input adjustment from the same table.
This hold time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or the data
Input. If this is true of the Global Clock Input, add the appropriate Input adjustment from
appropriate Input adjustment from the same table. When the hold time is negative, it is possible to change the data before the clock’s active
edge.
DCM output jitter is included in all measurements.

When writing to the Input
Flip-Flop (IFF), the time from
the setup of data at the Input pin
to the active transition at a
Global Clock pin. The DCM is in
use. No Input Delay is
programmed.
When writing to IFF, the time
from the setup of data at the
Input pin to an active transition
at the Global Clock pin. The
DCM is not in use. The Input
Delay is programmed.
When writing to IFF, the time
from the active transition at the
Global Clock pin to the point
when data must be held at the
Input pin. The DCM is in use.
No Input Delay is programmed.
When writing to IFF, the time
from the active transition at the
Global Clock pin to the point
when data must be held at the
Input pin. The DCM is not in
use. The Input Delay is
programmed.
