Clock-to-Output Times
TIOCKP
When reading from the Output
Flip-Flop (OFF), the time from the
active transition at the OCLK input to
data appearing at the Output pin

Propagation Times
TIOOP
The time it takes for data to travel from
the IOB’s O input to the Output pin

Set/Reset Times
TIOSRP
Time from asserting the OFF’s SR
input to setting/resetting data at the
Output pin
LVCMOS25(2), 12 mA output
drive, Fast slew rate
All

TIOGSRQ
Time from asserting the Global Set
Reset (GSR) input on the
STARTUP_SPARTAN3A primitive to
setting/resetting data at the Output pin

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 time requires adjustment whenever a signal standard other than LVCMOS25 with 12 mA drive and Fast slew rate is assigned to the data
Output. When this is true, add the appropriate Output adjustment from Table 29.
