Analog Devices Inc. EVAL-ADF7024DB4Z

Overview

EVAL-ADF7024DB4Z from Analog Devices is an evaluation board for the ADF7024 ultralow-power sub-GHz FSK/GFSK transceiver IC, supporting 431–435 MHz and 862–928 MHz ISM/SRD bands, data rates up to 300 kbps, and integrated packet handling with 240-byte Tx/Rx buffer. It enables rapid prototyping of battery-powered wireless sensor networks and IoT endpoints.

For engineers reviewing the EVAL-ADF7024DB4Z datasheet, EVAL-ADF7024DB4Z pinout, EVAL-ADF7024DB4Z application, or EVAL-ADF7024DB4Z equivalent, this board provides full SPI-accessible control of the ADF7024's smart wake mode, AFC/AGC, RSSI, integrated ADC, temperature sensor, and battery monitor - critical for low-duty-cycle remote sensing and regulatory-compliant (ETSI EN 300 220, FCC Part 15) designs.

Technical Context

The EVAL-ADF7024DB4Z implements the ADF7024 transceiver in a complete reference design with matched RF front-end, calibrated 26 MHz crystal oscillator, LFCSP-32 socketed IC interface, and configurable GPIOs (GP0–GP5, IRQ_GP3). It supports all six predefined radio profiles (9.6–300 kbps), automatic frequency control, image rejection calibration (U.S. Pat. 8,238,865 & 8,358,993), and autonomous carrier sense via Smart Wake Mode.

Board-level features include on-board 32 kHz RC oscillator, integrated 8-bit ADC with ADCIN_ATB3 input, battery voltage monitoring (1.7–2.7 V alarm range), and temperature sensing (−40°C to +85°C, ±4°C accuracy). Power delivery is optimized for 2.2–3.6 V operation with decoupling per ADF7024 regulator pins (CREGRF1/2, CREGVCO, CREGSYNTH, CREGDIG1/2).

FAQ

What is the primary function of the EVAL-ADF7024DB4Z evaluation board?

The EVAL-ADF7024DB4Z evaluation board is a fully assembled and tested hardware platform for evaluating the ADF7024 ultralow-power sub-GHz FSK/GFSK transceiver IC. It provides immediate access to all ADF7024 features-including SPI-controlled radio state transitions, Smart Wake Mode, integrated ADC, temperature sensor, and battery monitor-enabling rapid validation of wireless sensor node behavior without custom PCB design. The board includes matching networks, crystal oscillator, and power regulation aligned with ADF7024 datasheet requirements.

Does the EVAL-ADF7024DB4Z support FCC and ETSI regulatory testing?

Yes, the EVAL-ADF7024DB4Z implements the ADF7024 in a reference configuration validated for compliance with ETSI EN 300 220 and FCC Part 15.231, 15.247, and 15.249. Its layout follows Analog Devices' recommended RF practices, including proper grounding of the exposed pad, decoupling per regulator pins (CREGRF1/2, CREGVCO, etc.), and calibrated 26 MHz crystal placement. Users must still perform final system-level certification, but the EVAL-ADF7024DB4Z serves as a proven starting point for pre-compliance testing.

Can the EVAL-ADF7024DB4Z operate in low-power modes like PHY_SLEEP?

Yes, the EVAL-ADF7024DB4Z supports all ADF7024 power modes, including PHY_SLEEP (Deep Sleep Mode 1 at 0.33 µA with memory retained) and Smart Wake Mode with autonomous Rx sniffing (11.75 µA average at 300 kbps). The board routes the 32 kHz RC oscillator and CWAKEUP capacitor (150 nF) as specified, enabling host-processor-independent wake-up for carrier sense and packet reception - essential for extending battery life in intermittent-monitoring applications using the EVAL-ADF7024DB4Z.

What interfaces and peripherals are accessible on the EVAL-ADF7024DB4Z?

The EVAL-ADF7024DB4Z exposes the full ADF7024 SPI interface (SCLK, MOSI, MISO, CS), IRQ_GP3 interrupt pin, six general-purpose I/Os (GP0–GP5), analog inputs ADCIN_ATB3 and ATB4, and test points for ATB1/ATB2. It also includes on-board connections for the 26 MHz crystal (XOSC26P/XOSC26N), RF I/O (RFI_P/RFI_N, RFO), and all regulator supply pins (CREGRF1/2, CREGVCO, CREGSYNTH, CREGDIG1/2), allowing direct measurement and customization of biasing and filtering networks during EVAL-ADF7024DB4Z evaluation.

Is the ADF7024 IC socketed or soldered on the EVAL-ADF7024DB4Z board?

The ADF7024 IC is socketed on the EVAL-ADF7024DB4Z board using a precision LFCSP-32 socket compatible with the 5 mm × 5 mm, 32-lead lead-frame chip-scale package. This allows safe insertion and removal of the ADF7024 transceiver IC without soldering, facilitating device swapping, firmware reprogramming, and failure analysis - a key design feature of the EVAL-ADF7024DB4Z to support iterative development and multi-device comparison.
