ADF4382ABCCZ-RL7

Overview

The ADF4382ABCCZ-RL7 is a microwave wideband synthesizer with an integrated voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates as a fractional-N phase-locked loop (PLL) designed for ultralow jitter performance. The device supports a fundamental output frequency range of 11.5 GHz to 21 GHz and a divide-by-2 output range of 5.75 GHz to 10.5 GHz. It utilizes an SPI interface for control and is housed in a 48-LGA package.

Feature Summary

• Integrates a high-performance fractional-N PLL with a wideband VCO for compact system design
• Delivers ultralow jitter characteristics suitable for demanding RF applications
• Supports flexible frequency generation through fundamental and divided output modes

Applications

• Microwave communication systems requiring stable local oscillators
• Test and measurement equipment needing precise frequency synthesis
• Radar systems utilizing wideband signal generation

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the ABCCZ variant matches the required frequency bands of 11.5–21 GHz. Ensure compatibility with 3.3V or 5V logic levels if interfacing directly. Check for moisture sensitivity labels on received units. Validate that the LGA-48 footprint aligns with the PCB layout specifications.

Selection Notes

Select this component when wide bandwidth and low phase noise are critical. The integrated VCO simplifies design compared to external solutions. Consider the 48-LGA package size for space-constrained boards. Evaluate power consumption against system thermal limits. Verify SPI interface compatibility with the host microcontroller.

Part Context

This part belongs to the ADF4382 family of wideband synthesizers. It shares architectural similarities with other members but offers specific frequency coverage. The family targets high-frequency applications where integration reduces component count. Development tools like evaluation boards are available for testing.

Replacement Considerations

Direct substitutes include other ADF4382 variants such as ADF4382BCCZ-RL7, which may offer different frequency ranges or performance tweaks. Verify pinout compatibility before substitution. Check datasheet differences regarding output power and phase noise specifications.
