Notes:
1. Functional and tested operating conditions are given in
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 –0.3 to 2.75 V range is for DDR and –0.3 to 1.98 V range is for DDR2.
3. The 3.63 V maximum is only supported when the port is configured in GMII, MII, RMII, or TBI modes; otherwise the 2.75 V
maximum applies. See
for details on
the recommended operating conditions per protocol.
