2.2.2 Power Configurations and Jumper Settings

The AFE11612EVM provides electrical connections to the device supply pins. Table 2-1 shows these connections.

Table 2-1 AFE11612EVM Power Supply Inputs
AFE11612EVM Connector Supply Name Voltage Range
J1 VCC 1.8 V to 5.5 V
J2 VDD 1.8 V to 5.5 V (5 V available from the USB). Remove J6 if applying an external VDD to the AFE.
J3 VIO 1.8 V to 5.5 V
J4 GND 0 V

The jumper settings on the AFE11612EVM are crucial to the proper operation of the EVM. Table 2-2 provides the details of the configurable jumper settings on the EVM.
