8.3 Power Supply Recommendations

The DP83867 is capable of operating with as few as two or three supplies. The I/O power supply can also be operated independently of the main device power supplies to provide flexibility for the MAC interface.

For detailed information about DP83867 power consumption for specific supplies under a wide set of conditions, see the DP83867E/IS/CS/IR/CR RGZ Power Consumption Data application report (SNLA241).

The connection diagrams for the two-supply and three-supply configurations are shown in Figure 8-7 and Figure 8-8.

DP83867IR DP83867CR Two Supply Configuration
A. For two supply configuration, both VDDA1P8 pins must be left unconnected.
B. RGZ devices support 1.0V on VDD1P0 pins. PAP device support 1.1V on VDD1P1 pins
C. Place 1µF and 0.1µF decoupling capacitors as close as possible to component VDD pins, placing the 0.1µF capacitor closest to the pin.
D. VDDIO can be 3.3V or 2.5V or 1.8V.
E. No Components must be connected to VDDA1P8 pins in Two Supply Configuration.
Figure 8-7 Two Supply Configuration
DP83867IR DP83867CR Three Supply Configuration
A. Place 1µF and 0.1µF decoupling capacitors as close as possible to component VDD pins, placing the 0.1µF capacitor closest to the pin.
B. RGZ devices support 1.0V on VDD1P0 pins. PAP device support 1.1V on VDD1P1 pins
C. VDDIO can be 3.3V or 2.5V or 1.8V.
Figure 8-8 Three Supply Configuration

When operating in three-supply mode, the 1.8V VDDA1P8 supply must be stable within 25ms of the 2.5V VDDA2P5 supply ramping up. There is no sequencing requirement for other supplies when operating in three-supply mode.

When powering down the DP83867, the 1.8V supply must be brought down before the 2.5V supply.

Note:

If the 2.5V power supply provides power to DP83867 devices only, the 1.8V supply can ramp up any time before 2.5V.

There is no requirement for the sequence of the supplies when operating in two-supply mode.
