2.2 Hardware Setup

This section describes the overall system setup for the EVM. A local machine runs the software that provides an interface to the AFE882H1EVM through the onboard FTDI controller. The USB connection provides 5 V of power to the EVM. Low-dropout regulators (LDOs) generate the 3.3-V and 1.8-V supplies used for PVDD and IOVDD for use as the supply voltage across the EVM board. Optional external PVDD and IOVDD connections are available through banana jack terminals after the 3.3-V and the 1.8-V LDO supplies are disconnected. The XTR305 on the board requires +15-V and –15-V supplies for operation also through banana jack terminals.
