ADF4382 no-OS Example Project

The EV-ADF4382ASD2Z evaluates the performance of the ADF4382A frequency synthesizer with an integrated voltage-con-trolled oscillator (VCO) for phase-locked loops (PLLs). It contains the ADF4382A frequency synthesizer with an integrated VCO, a USB interface, power supply connectors, on-board reference oscillator, propagation delay calibration paths, and Subminiature Version A (SMA) connectors. The outputs of the EV-ADF4382ASD2Z are AC-coupled with 50 Ω transmission lines, making these outputs suitable to drive 50 Ω impedance instruments.

Full specifications for the ADF4382A frequency synthesizer are available in the ADF4382A data sheet, which must be consulted in conjunction with this user guide when working with the EV-ADF4382ASD2Z.

Applications

High Performance Data Converter Clocking
Wireless infrastructure (MC-GSM, 5G, 6G)
Test and Measurement

Hardware Specifications

Power Supply Requirements

The EV-ADF4382ASD2Z is powered by a 6 V power supply connected to the J18 SMA connector, or the J14 banana plug and GND to the J15 banana plug.

Reference Input Requirements

The EV-ADF4382ASD2Z has an on-board, 125 MHz, ultra low phase noise, sine-wave oscillator to drive the ADF4382A reference input. Single-ended oscillator output is connected to the REFP pin, and the REFN pin is AC grounded. This oscillator is used by default on the board.

The reference input can also be driven externally via a pair of SMA connectors, REFN (J4) and REFP (J11). When using the external reference, disable the on-board oscillator supply. This will require board modifications, please refer to the EVAL-ADF4382A User Guide for details.

No-OS Build Setup

Please see: https://wiki.analog.com/resources/no-os/build

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 ADF4382 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 and channel 0 is active with a power level of 9. Subsequently the example sets a test frequency of 3.1 GHz and adjusts the phase by 1ns.

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
BASIC_EXAMPLE = y
IIO_EXAMPLE = n

IIO example

This project provide an IIOD demo for the ADF4382. It launches an IIOD server on the mother platform it runs on allowing the user to connect via an IIOD client. Using IIO-Oscilloscope, the user can configure the ADF4382A.

If you are not familiar with ADI IIO Application, please take a look at: IIO No-OS

The No-OS IIO Application together with the No-OS IIO ADF4382 driver take care of all the back-end logic needed to setup the IIO server.

This example initializes the IIO device and calls the IIO app as shown in: IIO Example

In order to build the IIO project make sure you have the following configuration in: Makefile

# Select the example you want to enable by choosing y for enabling and n for disabling
BASIC_EXAMPLE = n
IIO_EXAMPLE = y
