ADF4107BRUZ

Overview

The ADF4107BRUZ is an Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates within a 1.0 GHz to 7.0 GHz RF input range and supports reference frequencies up to 250 MHz. The device functions on a 2.7 V to 3.3 V supply with a maximum current draw of 17 mA. Key features include a programmable dual-modulus prescaler (8/9, 16/17, 32/33, 64/65), a separate charge pump supply pin (VP) for extended tuning voltage, and a 3-wire serial interface. It is housed in a 16-lead TSSOP package.

Feature Summary

• Operates as an Integer-N PLL synthesizer with a 7.0 GHz bandwidth
• Supports programmable dual-modulus prescalers: 8/9, 16/17, 32/33, and 64/65
• Includes separate VP pin allowing charge pump supply up to 5.5 V for extended VCO tuning
• Features analog and digital lock detect capabilities with programmable antibacklash pulse width

Applications

• Local oscillators for broadband wireless access systems
• Local oscillators for satellite communication systems
• Local oscillators for wireless LAN infrastructure
• Base stations for wireless radio networks
• General instrumentation requiring precise frequency synthesis

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly from the latest datasheet revision, as manufacturing processes may update environmental declarations over time.

Selection Notes

Select this component when a high-bandwidth Integer-N synthesizer is required for frequencies up to 7 GHz. Ensure the external VCO tuning voltage requirements are met by utilizing the separate VP supply pin if voltages exceed the standard AVDD level. Verify that the system loop filter design accommodates the programmable charge pump currents ranging from 625 µA to 5 mA.

Part Context

The ADF4107 belongs to the ADF4107 family of frequency synthesizers. It serves as a core phase-locked loop component designed to work with external voltage-controlled oscillators (VCOs) and passive loop filters. The BRUZ suffix indicates the B version operating temperature range (-40°C to +85°C) and the TSSOP-16 surface-mount package.
