The schematic diagram for the this EVM is attached at the end of this document. See the schematic or
relevant section of this user's guide before changing any jumpers.
Selection of various modes of operation of the ADS62PXX EVM is most often controlled by jumpers on the
EVM, either by placing shunts on 0.025-inch square jumper posts or by installation of surface mount 0 Ω
resistors. In general, the use of 0 Ω resistors as jumpers are used in the clock or signal path where signal
integrity is critical, and jumper posts are used for static or low-speed control paths. Figure 1 shows the
relative location of the jumpers, connectors, and switches used on the ADS62PXX EVM. Figure 2 shows
the relative locations of most of the resistors and surface-mount 0 Ω jumper locations used on the EVM. In
the description of the circuit options in the following sections, each operational mode is accompanied by a
table entry that details the jumper or resistor changes that enable that option. Figure 1 and Figure 2 can
assist the user to quickly identify where these jumpers are located on the EVM.
