These values satisfy the MII specification requirement of 0 ns to 25 ns clock to output delay.
These values satisfy the MII specification requirement of 10-ns setup and hold time.
Timing tests were performed with a 70-pF capacitor to ground.
This parameter has been simulated but has not been fully tested.
