Eval Board Jumper Options

There are 7 pin jumpers on the evaluation board. The pin jumpers are corresponding to the 6 supplies on the board. They serve as

‘switches’ that determine if the LDOs on board or external supplies are used for each individual supply. They are shunted by default,

which means on board LDOs are used. When an external supply is necessary, pull off the shunt from the corresponding supply and

connect the external supply to the SMA jack close to the jumper. The seventh pin jumper configures the voltage of the IOVDD supply.
