The evaluation board is configured at assembly to use the
AD9214’s on-board reference. To supply an external reference,
the user must connect the REFSENSE pin to VCC by removing
the jumper block connecting E25 to E26, and placing it between
E19 and E24. In this configuration, an external 1.25 V reference
must be connected to jumper connection E23. Jumper connections
E19–E21, E24, and resistors R13–R14 are omitted at assembly,
and not used in the evaluation of the AD9214.
