ADF4107BRUZ-REEL7

Overview

The ADF4107BRUZ-REEL7 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 power supplies from 2.7 V to 3.3 V, with a separate charge pump supply (VP) up to 5.5 V for extended tuning voltage. The device features a programmable dual-modulus prescaler (8/9, 16/17, 32/33, or 64/65), a 14-bit reference counter, and a 19-bit N divider composed of 6-bit A and 13-bit B counters. It includes a low-noise digital phase-frequency detector, a precision charge pump with programmable currents, and a 3-wire serial interface. The component is housed in a 16-pin TSSOP package.

Feature Summary

• Operates as an Integer-N PLL synthesizer with a 7.0 GHz bandwidth and 1.0 GHz to 7.0 GHz RF input frequency range.
• Features a programmable dual-modulus prescaler with options for 8/9, 16/17, 32/33, or 64/65 division ratios.
• Includes a separate charge pump supply pin (VP) allowing extended tuning voltages up to 5.5 V while maintaining a 2.7 V to 3.3 V core supply.
• Integrates analog and digital lock detect functions alongside a 3-wire serial interface for configuration.

Applications

• Local oscillators in broadband wireless access systems
• Local oscillators in satellite communication systems
• Frequency synthesis for wireless LANs
• Base station transmitters for wireless radio applications

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the B version temperature rating of -40°C to +85°C aligns with the intended operational environment. Ensure the 16-pin TSSOP footprint matches the PCB design specifications before finalizing procurement orders.

Selection Notes

Select this component when a high-bandwidth Integer-N synthesizer is required for frequencies up to 7 GHz. The separate VP supply pin is critical if the external VCO requires a tuning voltage exceeding the 3.3 V logic supply. Verify that the maximum PFD frequency of 104 MHz and the prescaler output limit of 300 MHz are compatible with the chosen reference and feedback divider settings.

Part Context

This part belongs to the ADF4107 series of frequency synthesizers from Analog Devices. The BRUZ suffix indicates the industrial temperature grade (-40°C to +85°C) and the TSSOP-16 surface-mount package. The REEL7 designation specifies the reel quantity and packaging method used for manufacturing distribution.
