The numbers in this table are tested using the methodology presented in
Table 6
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
the 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.
and
R
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 used. 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 used.
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 used. 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 used. The Input Delay
