1.3 EVM Connectors and Jumpers
Figure 3. ADS4449 EVM Connector and Jumper Locations
The locations of the connectors, jumpers, pushbutton switches, and LEDs are shown in Figure 3 . The
EVM has power connectors or banana jacks connecting the main power for power distribution. The SMA
connectors connect the ADC input and ADC clock input to the ADC. Typically, the ADC inputs are
transformer coupled, accepting single-ended connections. The input circuit can be configured to connect
to two SMA connectors for differential signaling.
Table 2 lists the connector information for the EVM.
