2.2 Power Requirements

The AM2x EVM Industrial Ethernet PHY Add-on Board is powered from 2.5V and 3.3V inputs from the DF40GB 48-pin connector that interfaces the DP83TG720-EVM-AM2 with the main MCU EVM. There is an on-board LDO that steps the 2.5V input down to 1.0V to supply the DP83TG720S-Q1 VDD inputs. The following sections describe the power distribution network topology that supply the AM2x EVM Industrial Ethernet PHY Add-on Board, supporting components, and reference voltages.
