ADF5902 no-OS Example Project

See projects/adf5902_sdz (doxygen) for the Doxygen documentation.

Supported Evaluation Boards

• EV-ADF5902SD1Z

Overview

The ADF5902 is a 24 GHz ISM band VCO and PGA with 2-channel transmitter designed for FMCW radar applications. It features a 24 GHz to 24.25 GHz VCO, a 2-channel 24 GHz power amplifier with 8 dBm output, and an on-chip temperature sensor. The device supports frequency ramp generation and calibration for automotive and industrial radar systems.

The EV-ADF5902SD1Z evaluation board enables characterization of the ADF5902 device. It interfaces with an FPGA platform via SPI and GPIO using the SDP-I-FMC interposer board.

Applications

• Automotive radars

• Industrial radars

• Microwave radar sensors

No-OS Build Setup

Please see: No-OS Build Guide

No-OS Supported Examples

The initialization data used in the examples is taken out from the Project Source Data Path.

Application example

This is the default example which initializes the ADF5902 device, performs calibration using adf5902_recalibrate, computes the locked frequency with adf5902f_compute_frequency, and reads the on-chip temperature sensor with adf5902_read_temp.

No-OS Supported Platforms

Xilinx

Used Hardware

• EV-ADF5902SD1Z

• Zedboard

• SDP-I-FMC Interposer

Connections

Connect the EV-ADF5902SD1Z to the Zedboard via the SDP-I-FMC interposer board. The SPI interface and GPIO signals (CE, TX_DATA) are managed by the Xilinx PS7 peripherals.
