Electrical Characteristics
(continued)
* These parameters are for clock pulses within an FPGA device. For externally applied clock, increase values by 20%.
Note: The CLB K to Q output delay (TCKO—#8) of any CLB, plus the shortest possible interconnect delay, is always longer than the data in
hold time requirement (TCKDI—#5) of any CLB on the same die.
