Notes:
1. Functional operating conditions are given in Table 2. Absolute maximum ratings are stress ratings only, and functional
operation at the maximums is not guaranteed. Stresses beyond those listed may affect device reliability or cause permanent
damage to the device.
2. The 3.63V maximum is only supported when the port is configured in GMII, MII, RMII or TBI modes; otherwise the 2.75V
maximum applies. See Section 8.2, “FIFO, GMII, MII, TBI, RGMII, RMII, and RTBI AC Timing Specifications,” for details on
the recommended operating conditions per protocol.
3. (M,L,O)V may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.
