Clock-to-Output Times
T
The numbers in this table are tested using the methodology presented in
Table 6
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 used.
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 used.
