OR3Cxx Commercial: V
OR3Txxx Commercial: V
50 pF.
Notes:
Timing is without the use of the programmable clock manager (PCM).
This clock delay is for a fully routed clock tree that uses the ExpressCLK network. It includes both the input buffer delay, the clock routing to the
PIO CLK input, the clock Q of the FF, and the delay through the output buffer. The given timing requires that the input clock pin be located at
one of the six ExpressCLK inputs of the device, and that a PIO FF be used.
