Input & Output Standard Timing Delay Adjustments
All the timing specifications in this data sheet are specified based on 3.3V PCI compliant inputs and outputs (fast slew rates).[14]
Apply following adjustments if the inputs and outputs are configured to operate at other standards.

Notes:
14. For “slow slew rate” output delay adjustments, refer to Warp software’s static timing analyzer results.
15. These delays are based on falling edge output. The rising edge delay depends on the size of pull up resistor and termination voltage.
