2.2 Power Requirements

The EVM Industrial Ethernet PHY Add-on Board is powered from a 3.3V input from the DF40GB 48-pin connector that interfaces the DP83867-EVM-AM with the main EVM. The following sections describe the power distribution network topology that supply the EVM Industrial Ethernet PHY Add-on Board, supporting components, and reference voltages.
