Note:

1 GV

DD, NVDD, AVDD, and VDD must track each other and must vary in the same direction—either in the positive or negative

direction.

2 NV

DD here refers to NVDDA, NVDDB,NVDDG, NVDDH and NVDDP_K from the ball map.

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

4 LV

DD1 here refers to NVDDC and LVDD2 refers to NVDDF from the ball map.

5 Minimum temperature is specified with T

A; Maximum temperature is specified with TJ.
