ADF4107BCPZ-REEL7

Overview

The ADF4107BCPZ-REEL7 is an Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates within a 2.7 V to 3.3 V supply range 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 14-bit reference counter. Key electrical parameters include a maximum phase detector frequency of 104 MHz, a typical operating current of 15 mA at 3 V, and a power-down mode consuming 10 µA. It utilizes a 3-wire serial interface for configuration and includes both analog and digital lock detect capabilities.

Feature Summary

• Supports RF input frequencies up to 7.0 GHz with a 2.7 V to 3.3 V power supply
• Programmable dual-modulus prescaler options: 8/9, 16/17, 32/33, and 64/65
• Integrated low-noise digital phase frequency detector and precision charge pump
• Provides separate charge pump supply (VP) pin for extended tuning voltage in 3 V systems

Applications

• Broadband wireless access systems
• Satellite communication systems
• Wireless LAN infrastructure
• Base stations for wireless radio networks
• General instrumentation requiring local oscillators

Procurement Notes

Verify the specific package type against the ordering suffix. The datasheet indicates the B version operates from -40°C to +85°C. Confirm that the REEL7 suffix corresponds to the tape and reel packaging format intended for automated assembly processes. Ensure compatibility with the LFCSP-20 footprint if selecting this variant.

Selection Notes

Select the appropriate dual-modulus prescaler value (P) based on the desired RF output frequency to ensure the prescaler output remains below 300 MHz. The N divider ratio is calculated as N = BP + A. Ensure the external loop filter and VCO are compatible with the charge pump currents and tuning voltage requirements provided by the VP pin.

Part Context

The ADF4107 is part of the ADF4107 family of integer-N PLL frequency synthesizers. It is designed to implement local oscillators in wireless receiver and transmitter architectures. The device simplifies system design by offering high bandwidth, which can eliminate the need for frequency doublers in many high-frequency applications.
