9.3 Power Supply Recommendations

The DP83TC813S-Q1is capable of operating with a wide range of IO supply voltages (3.3V, 2.5V, or 1.8V). No power supply sequencing is required. Please note that inputs pins must not be driven until VDDA and VDDIO are stable. The recommended power supply de-coupling network is shown in the figure below. For improved conducted emissions, an optional ferrite bead can be placed between the supply and the PHY de-coupling network.

Typical TC-10 application block diagram along with supply and peripherals is shown below. TPS7B81-Q1 is the recommended part number to be used as 3.3V LDO for the VSLEEP rail. The low quiescent current of this LDO makes the LDO designed for TC-10 applications.

When VDDIO and VDDMAC are separate, both voltage rails must have a dedicated network of ferrite bead, 0.47µF, and 0.01µF capacitors. VSLEEP can also be connected to VDDA, 0.1µF capacitor must be retained in this configuration.

Current Consumption Break-Down

The following table highlights the break down of power consumption in active mode for each supply rail, specifically highlighting the split between VDDMAC and VDDIO.
