Analog supply. 2.5V. AVDD can be supplied exter-
nally with 2.5V, or via the 2.5V regulator.
Analog supply - 2.5V or 3.3V.
AVDDC must be supplied externally. Do not use
the 2.5V regulator to power AVDDC.
1.2V Regulator supply - 2.5V
AVDDR can be supplied externally with 2.5V, or via
the 2.5V regulator. If the 1.2V regulator is not used,
AVDDR must still be tied to 2.5V.
2.5V Regulator supply - 3.3V
AVDDX must be supplied externally. Note that this
supply must be the same voltage as AVDDC.
If the 2.5V regulator is not used, then it means a
2.5V supply is in the system. AVDDX should be left
floating.
Digital core supply - 1.2V.
DVDD can be supplied externally with 1.2V, or via
the 1.2V regulator.
2.5V or 3.3V non-MAC Interface digital I/O supply.
VDDO must be supplied externally. Do not use the
2.5V regulator to power VDDO.
VDDOR must be supplied externally. Do not use
the 2.5V regulator to power VDDOR.
Ground to digital core.
The 64-pin QFN package has an exposed die pad
(E-PAD) at its base. This E-PAD must be soldered
to VSS. Refer to the package mechanical drawings
for the exact location and dimensions of the EPAD.
and can be tied to anything.
2.5V or 3.3V MAC Interface digital I/O supply.
No Connect. These pins are not bonded to the die
