OR3Txxx Commercial: V
Notes:
The ECLK delays are to all of the PICs on one side of the device for middle pin input, or two sides of the device for corner pin input. The delay
includes both the input buffer delay and the clock routing to the PIC clock input.
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.
