TIOICKPD
Time from the active transition at the
ICLK input of the Input Flip-Flop (IFF)
to the point where data must be held
at the Input pin. The Input Delay is
programmed.

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 setup time requires adjustment whenever a signal standard other than LVCMOS25 is assigned to the data Input. If this is true, add the
appropriate Input adjustment from Table 26.
3.
These hold times require adjustment whenever a signal standard other than LVCMOS25 is assigned to the data Input. If this is true, subtract
the appropriate Input adjustment from Table 26. When the hold time is negative, it is possible to change the data before the clock’s active
edge.

The input capture sample window value is highly specific to a particular application, device,
package, I/O standard, I/O placement, DCM usage, and clock buffer. Please consult the
appropriate Xilinx Answer Record for application-specific values.
