Supported Evaluation Boards
Overview
The EV-ADF4371SD2Z evaluates the performance of the ADF4371 frequency synthesizer with an integrated voltage controlled oscillator (VCO) for phase-locked loops (PLLs). The evaluation board contains the ADF4371 frequency synthesizer with an integrated VCO, a USB interface, power supply connectors, and subminiature Version A (SMA) connectors.
Full specifications for the ADF4371 frequency synthesizer are available in the ADF4371 data sheet, which must be consulted in conjunction with this user guide when working with the evaluation board.
Applications
Wireless infrastructure (multicarrier global system for mobile communication (MC-GSM), 5 G)
Test equipment and instrumentation
Clock generation
Aerospace and defense
Hardware Specifications
Power Supply Requirements
The EV-ADF4371SD2Z is powered by a 6 V power supply connected to the VUSPPL SMA connector, or the P2 banana plug and GND to the P4 banana plug.
Reference Input Requirements
The EV-ADF4371SD2Z board is supplied with a low noise 100 MHz crystal oscillator (XO) from Crystek (CCHD-575-50- 100.000).
To use an external single-ended REF IN, connect a low noise reference source to the REFP SMA connector. Remove Resistor R19 (0 Ω) and Resistor R20 (0 Ω) to remove power from the crystal and break the connection to the REFP input.

No-OS Supported Examples
The initialization data used in the examples is taken out from: Project Common Data Path
The macros used in Common Data are defined in platform specific files found in: Project Platform Configuration Path
Basic example
This example initializes the ADF4371 with the configurations provided in the above mentioned common files and applies them to the IC. By default reference frequency is provided by the local oscillator of the board. Subsequently the example sets a test frequency of 8 GHz to channel 0 (RF8).
In order to build the basic example make sure you have the following configuration in the Makefile Makefile
# Select the example you want to enable by choosing y for enabling and n for disabling
