Clock-to-Output Times
T
The numbers in this table are tested using the methodology presented in
Table 10
This clock-to-output time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the Global Clock Input or a
standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned to the data Output. If the former is true, add the appropriate
Input adjustment from
DCM output jitter is included in all measurements.

When reading from the Output
Flip-Flop (OFF), the time from the
active transition on the Global
Clock pin to data appearing at the
Output pin. The DCM is in use.
When reading from OFF, the time
from the active transition on the
Global Clock pin to data appearing
at the Output pin. The DCM is not
in use.
