1. AVDD supplies the MDIP/N[3:0] pins.
2. AVDDC supplies the XTAL_IN and XTAL_OUT pins.
3. VDDO supplies the MDC, MDIO, RESETn, LED[2:0], CONFIG[3:0], TDI, TMS, TCK, TRSTn, TDO, DIS_REG12,
4. VDDOR supplies the TXD[3:0], TX_CLK, TX_CTRL, RXD[3:0], RX_CLK, and RX_CTRL pins.
5. Pin 28 must be connected to AVDD in Revision A0. Refer to the Rev A0 Release Notes for Pin 28 connection

88E1118R Technical Product Brief
Document Classification: Proprietary Information
Desc ription
Analog supply. 1.8V
1.8V regulator.
Analog supply - 1.8V or 2.5V, or 3.3V
AVDDC must be supplied externally. Do not use the 1.8V regulator to power
AVDDC.
1.2V Regulator supply - 1.8V
AVDDR can be supplied externally with 1.8V, or via the 1.8V regulator. If the
1.2V regulator is not used, AVDDR must still be tied to 1.8V.
1.8V Regulator supply - 2.5V, 3.3V, (or 1.8V).
AVDDX must be supplied externally. Note that this supply must be the same
voltage as AVDDC.
If the 1.8V regulator is not used, then it means a 1.8V supply is in the sys-
tem. AVDDX (along with AVDDC) would be tied to 1.8V in this case.
Digital core supply - 1.2V.
DVDD can be supplied externally with 1.2, or via the 1.2V regulator.
1.8V, 2.5V, or 3.3V non-RGMII digital I/O supply
VDDO must be supplied externally. Do not use the 1.8V regulator to power
VDDO.
1.8V, 2.5V, or 3.3V RGMII digital I/O supply
VDDOR must be supplied externally. Do not use the 1.8V regulator to power
VDDOR.
Ground to device. 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 dimen-
sions of the EPAD.
No connect. These pins are not connected to the die so they can be con-
nected to anything on the board.
