Timing Characteristics (continued)

Table 57. OR3LP26B Input to Fast Clock Setup/Hold Time (Pin-to-Pin)

OR3LP26B Commercial: VDD = 3.0 V to 3.6 V, 0 °C < TA < 70 °C; VDD2 = 2.38 V to 2.63 V, 0 °C < TA < 70 °C.

Notes:

The pin-to-pin timing parameters in this table should be used instead of results reported by

ORCA Foundry.

The fclk delays are for a fully routed clock tree that uses the ExpressCLK input into the fast clock network. It includes both the input buffer delay

and the clock routing to the PFU CLK input. The delay will be reduced if any of the clock branches are not used.
