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 used.
TICKOF
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.

Notes:
1. The numbers in this table are tested using the methodology presented in Table 19 and are based on the operating conditions set forth in
Table 6 and Table 9.
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 17. If the latter is true, add the appropriate Output adjustment from Table 18.
3. DCM output jitter is included in all measurements.
4. For minimums, use the values reported by the Xilinx timing analyzer.
