3.1 Power Supply Selection

Dual Supply Mode vs. Triple Supply Mode

The DP83561-SP can be powered by as few as two supplies in dual supply mode, or three supplies in triple supply mode. In dual supply mode, the VDDA1P8 pin must be left floating. By default the DP83561EVM is configured for dual supply mode. To configure the DP83561-SP in triple supply mode:

Place shunt on J37 to enable the SUPPLYMODE_SEL strap as described in Section 3.2

The following sections describe powering the DP83561EVM using the on-board LDOs, external supplies, or USB power. Please note that powering the VDDA1P8 pin is only required in triple supply Mode.
