By default, the analog input for the ADC354xEVM is configured for an AC-coupled, balun signal chain. For best spurious performance, the input frequency should be above 2 MHz.
For DC-coupled inputs, and those below 2 MHz, the FDA input path should be used. This can be done by making the following modifications to the EVM:
Once these modifications are performed, the analog input must be connected to J10.
