3.1 Hardware Requirements

This reference design is the analog front end (AFE) with connections provided to integrate with an external ADC EVM through its SMA connectors. An example for the full setup is shown below with ADC12J5200RFEVM. Other ADC EVM could also be used that are within these reference design levels.

This AFE reference design can be evaluated by itself using the USB2ANY controller as described in section Section 3.2.2
