ADF4371BCCZ-RL7

Overview

The ADF4371BCCZ-RL7 is a microwave wideband synthesizer with an integrated VCO, manufactured by Analog Devices Inc. It supports fractional-N and integer-N phase-locked loop (PLL) configurations to generate RF output frequencies ranging from 62.5 MHz to 32 GHz. The device features a high-resolution 39-bit fractional modulus and operates with programmable divide-by circuits for multiple output stages. Key electrical parameters include a reference frequency operation up to 600 MHz, a phase detector frequency up to 250 MHz in integer mode, and an integrated RMS jitter of 38 fs. Power supplies require 3.15 V to 3.45 V for analog/digital sections and 4.75 V to 5.25 V for the VCO.

Feature Summary

• Wideband frequency synthesis from 62.5 MHz to 32 GHz using an integrated VCO core operating at 4 GHz to 8 GHz.
• Multiple differential RF outputs including RF8x (62.5–8 GHz), RF16x (8–16 GHz), and RF32x (16–32 GHz).
• High-resolution 39-bit fractional modulus with normalized phase noise floor of -234 dBc/Hz.
• Fast lock time capability of less than 30 μs when autocalibration is bypassed.

Applications

• Wireless infrastructure systems including multicarrier GSM and 5G base stations.
• Test equipment and instrumentation requiring precise clock generation.
• Aerospace and defense radar and communication systems.

Procurement Notes

Verify that the ordering suffix RL7 corresponds to the reel packaging format specified in the manufacturer's documentation. Confirm the component meets RoHS compliance standards as indicated in the product specifications. Ensure the LGA-48 package handling procedures are followed during assembly due to moisture sensitivity classification.

Selection Notes

Select this component for applications requiring ultra-wideband frequency coverage up to 32 GHz. Consider the power supply requirements, specifically the separate 5 V rail for the VCO section, when designing the power architecture. Evaluate the thermal resistance characteristics and PCB layout guidelines to ensure adequate heat dissipation for the LGA-48 package under maximum load conditions.

Part Context

The ADF4371BCCZ-RL7 belongs to the ADF4371 series of microwave wideband synthesizers. It shares the same functional block diagram and core specifications as the tray-packaged ADF4371BCCZ variant, differing primarily in the shipping configuration. The device integrates a voltage-controlled oscillator, charge pump, and digital control logic into a single 7 mm × 7 mm LGA package.
