Notes:

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: OVIN must not exceed NVDD 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. Caution: LVIN must not exceed LVDD 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.

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

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

7. NVDD here refers to NVDDA, NVDDB,NVDDG, NVDDH, NVDDP_K from the ball map.

8. LVDD1 here refers to NVDDC and LVDD2 refers to NVDDF from the ball map
