ADF4107BRU-REEL

Overview

The ADF4107BRU-REEL is an Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates with a supply voltage range of 2.7 V to 3.3 V and supports RF input frequencies from 1.0 GHz to 7.0 GHz. The device features a programmable dual-modulus prescaler (8/9, 16/17, 32/33, or 64/65) and a separate charge pump supply pin (VP) allowing extended tuning voltages up to 5.5 V. Key electrical parameters include a maximum phase detector frequency of 104 MHz, a typical operating current of 15 mA, and a power-down mode current of 10 µA. It utilizes a 3-wire serial interface for configuration.

Feature Summary

• Integrated low-noise digital phase-frequency detector and precision charge pump with programmable currents.
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, and 64/65.
• Separate charge pump supply (VP) enables extended tuning voltage in 3 V systems.
• Hardware and software power-down modes reduce power consumption.

Applications

• Broadband wireless access systems
• Satellite communication systems
• Wireless LANs
• Base stations for wireless radio
• Instrumentation

Procurement Notes

Verify the specific package type required, as the ADF4107 series includes both TSSOP-16 (BRU suffix) and LFCSP-20 (BCPZ suffix) variants. Confirm that the REEL packaging matches the production volume needs. Check for end-of-life status or discontinuance notices from Analog Devices prior to finalizing procurement plans.

Selection Notes

Select the ADF4107 when high bandwidth is required to eliminate external frequency doublers in high-frequency systems. Ensure the reference input frequency falls within the 20 MHz to 250 MHz range. Verify that the external VCO tuning voltage requirements are met by utilizing the VP pin if the system supply is limited to 3 V.

Part Context

The ADF4107 belongs to the ADF4107 family of integer-N frequency synthesizers. It is designed to implement local oscillators in upconversion and downconversion sections of wireless receivers and transmitters. The BRU-REEL designation indicates the TSSOP-16 package variant supplied in reel packaging.
