ADF4002BRUZ-RL7

Overview

The ADF4002BRUZ-RL7 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 a maximum RF input frequency of 400 MHz and a reference input frequency up to 300 MHz. It features a 104 MHz phase detector, programmable charge pump currents ranging from 625 µA to 5 mA, and a separate charge pump supply (VP) allowing extended tuning voltage in 3 V systems. Packaged in a TSSOP-16 surface-mount format, it functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated low-noise digital phase frequency detector (PFD) and precision charge pump
• Programmable 14-bit R counter and 13-bit N counter for flexible frequency synthesis
• Three-wire serial interface for register configuration
• Separate VP pin allows charge pump operation up to 5.5 V while logic remains at 3.3 V

Applications

• Clock conditioning and generation
• Local oscillator (LO) generation for IF stages
• Wireless receiver and transmitter upconversion/downconversion sections

Procurement Notes

Verify the specific suffix RL7 corresponds to the reel packaging format when sourcing. Confirm that the B version grade meets the required -40°C to +85°C operating temperature range. Ensure the external loop filter and VCO are compatible with the device's charge pump current settings and tuning voltage requirements provided by the VP pin.

Selection Notes

Select this component for applications requiring a standalone PFD and charge pump or a complete integer-N PLL when paired with external components. Consider the programmable charge pump currents and antibacklash pulse width controls if minimizing phase noise and reference spurs is critical. Verify that the 400 MHz RF input limit aligns with the target local oscillator frequencies.

Part Context

This part belongs to the ADF4002 series of frequency synthesizers. The BRUZ designation indicates the RoHS-compliant TSSOP-16 package variant, while the -RL7 suffix specifies the reel packaging quantity. It serves as a core building block for generating stable clock signals in RF communication systems.
