Notes:

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 This voltage is the input to the filter discussed in Section 23.2, “PLL Power Supply Filtering,” and not necessarily the voltage

at the AVDD pin, which may be reduced from VDD by the filter.

3 NV

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

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

5 LV

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

6 Minimum temperature is specified with T

A; Maximum temperature is specified with TJ.
