Note:

1. Functional and tested 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. Caution: MVIN must not exceed GVDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms during

power-on reset and power-down sequences.

3. Caution: (N,L)VIN must not exceed (N,L)VDD by more than 0.3 V. This limit may be exceeded for a maximum of 20 ms

during power-on reset and power-down sequences.

4. (M,N,L)VIN and MVREF may overshoot/undershoot to a voltage and for a maximum duration as shown in Figure 2.

5. NVIN on the PCI interface may overshoot/undershoot according to the PCI Electrical Specification for 3.3-V operation, as

shown in Figure 2.

6. The max value of supply voltage should be selected based on the RGMII mode.

7. NVDD means NVDD1_OFF, NVDD1_ON, NVDD2_OFF, NVDD2_ON, NVDD3_OFF, NVDD4_OFF

8. LVDD means LVDD1_OFF and LVDD2_ON
