ADF4002BRUZ-RL

Overview

The ADF4002BRUZ-RL is an Integer-N phase detector and frequency synthesizer manufactured by Analog Devices Inc. It operates on a 2.7 V to 3.3 V power supply with a typical current consumption of 5 mA at 3 V. The device supports RF input frequencies from 5 MHz to 400 MHz and reference inputs up to 300 MHz. Key internal components include a low-noise digital phase frequency detector (PFD), a precision charge pump, a 14-bit R counter, and a 13-bit N counter. It features a 3-wire serial interface, programmable charge pump currents, and separate analog/digital supplies.

Feature Summary

• Integrated low-noise digital PFD and precision charge pump for integer-N synthesis
• Programmable 14-bit R counter and 13-bit N counter for flexible frequency division
• Separate charge pump supply pin (VP) allows extended tuning voltage in 3 V systems
• Supports both analog and digital lock detect functions via MUXOUT

Applications

• Clock conditioning and generation
• Local oscillator (LO) generation for IF stages
• Upconversion and downconversion sections in wireless receivers and transmitters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Confirm that the component meets RoHS compliance requirements as indicated in the datasheet. Ensure the supply voltage range matches the system design constraints of 2.7 V to 3.3 V for AVDD and DVDD.

Selection Notes

Select this component when implementing local oscillators requiring low phase noise and jitter. Ensure the external loop filter and VCO are compatible with the programmable charge pump currents. Verify that the required output frequency spacing aligns with the capabilities of the 14-bit R counter and 13-bit N divider.

Part Context

The ADF4002BRUZ-RL belongs to the ADF4002 series of frequency synthesizers. It is designed for wireless communication applications where precise clock generation is critical.
