3.7.1 Power Configuration

The default configuration of the AFE881H1EVM allows the board to be powered from the 3p3V line coming from the USB2ANY. Jumper J3 connects power from the 3p3V line to the PVDD and IOVDD pins of the device. To use external power supplies, remove the jumpers in J3 to connect supplies to J1 and J4 for connections to PVDD and IOVDD. When the external supply is 1.8 V, install R1 on the board; this resistor is not installed by default. Provide the external 1.8-V supply to PVDD, VDD, and IOVDD through J1 and J4.
