ADF4116BRUZ

Overview

The ADF4116BRUZ is a single Integer-N RF PLL frequency synthesizer from Analog Devices, designed for local oscillator implementation in wireless communication systems. It operates with an input frequency range of 80 MHz to 550 MHz and supports power supplies from 2.7 V to 5.5 V. The device features a dual-modulus prescaler (8/9), a low-noise digital phase-frequency detector, and a precision charge pump with selectable current levels. It utilizes a 3-wire serial interface for register control and includes Fastlock mode for rapid settling times. The component is available in a 16-lead TSSOP package.

Feature Summary

• Integrated Integer-N PLL with 8/9 dual-modulus prescaler
• RF input frequency range: 80 MHz to 550 MHz
• Power supply voltage range: 2.7 V to 5.5 V
• Fastlock mode for reduced lock time
• Digital lock detect output

Applications

• Base stations for wireless radio (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless handsets (GSM, PCS, DCS, CDMA, WCDMA)
• Wireless LANs
• Communications test equipment
• CATV equipment

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm temperature grade and packaging type. The BRUZ designation indicates the industrial temperature range (-40°C to +85°C) and TSSOP-16 package. Confirm RoHS compliance status through official documentation prior to integration.

Selection Notes

Select the ADF4116BRUZ when the required RF input frequency does not exceed 550 MHz. Ensure the application requires an Integer-N architecture rather than Fractional-N. Verify that the system power supply falls within the 2.7 V to 5.5 V range and that the 16-lead TSSOP footprint is compatible with the PCB design.

Part Context

The ADF4116BRUZ belongs to the ADF411x family, which also includes the ADF4117 (up to 1.2 GHz) and ADF4118 (up to 3.0 GHz). These devices share similar internal architectures and control interfaces but differ primarily in their maximum operating frequencies and prescaler configurations.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source material. For frequency ranges up to 1.2 GHz, the ADF4117 series may be considered. For ranges up to 3.0 GHz, the ADF4118 series is applicable.
