SLAU858B December 2023 – June 2025 AFE881H1
This section describes the overall system setup for the EVM. A computer runs the AFE88xH1EVM-GUI and provides an interface to the AFE881H1EVM through the onboard FTDI controller. The USB connection provides 5V of power to the EVM. Low-dropout regulators (LDOs) generate the 3.3V and 1.8V supplies used for PVDD, IOVDD, and VDD for use as the supply voltage across the EVM board. Optional external PVDD, IOVDD, and VDD connections are available through banana jack terminals after the 3.3V and the 1.8V LDO supplies are disconnected. An external VDD connection is only needed if PVDD is 1.8V.
