Clock-to-Output Times
TICKOFDCM
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.

Notes:
1.
The numbers in this table are tested using the methodology presented in Table 30 and are based on the operating conditions set forth in
2.
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 Table 26. If the latter is true, add the appropriate Output adjustment from Table 29.
3.
DCM output jitter is included in all measurements.
