All MII Interface pins comply with IEEE 802.3u timing specifications (See Reconciliation Sub-layer and Media Independent
Interface in IEEE 802.3u timing specifications). All digital output timing specified at C
Output rise/fall times measured between 10% and 90% of the output signal swing. Input rise/fall times measured between
V
referenced to the midpoint between V
for an illustration of clock and reset timing.
