ADF4106BRU-REEL7

Overview

The ADF4106BRU-REEL7 is a single-channel, integer-N PLL frequency synthesizer from Analog Devices. It operates with a 2.7 V to 3.3 V power supply and supports RF input frequencies from 500 MHz to 6.0 GHz. The device integrates a low-noise digital phase-frequency detector, a precision charge pump, programmable reference and N counters (N = BP + A), and a dual-modulus prescaler. Key electrical parameters include a maximum PFD frequency of 104 MHz, a typical operating current of 9.0 mA at 3 V, and a separate charge pump supply (VP) allowing extended tuning voltage up to 5.5 V in 3 V systems.

Feature Summary

• 6.0 GHz bandwidth with integrated dual-modulus prescaler (8/9, 16/17, 32/33, 64/65)
• Programmable charge pump currents ranging from 625 µA to 5 mA
• Analog and digital lock detect capabilities with MUXOUT access
• Hardware and software power-down modes for low standby current

Applications

• Local oscillators for broadband wireless access base stations
• Satellite communication system transceivers
• Wireless LAN infrastructure equipment
• Instrumentation and test equipment local oscillators

Procurement Notes

Verify the specific suffix 'R7' indicates reel packaging when sourcing. Confirm the B version temperature range (-40°C to +85°C) matches application requirements. Ensure the external loop filter and VCO are compatible with the device's RF input sensitivity and charge pump output characteristics.

Selection Notes

Select this component for high-bandwidth applications where frequency doublers can be eliminated. Ensure the prescaler value selection keeps the divided RF frequency below 325 MHz for the CMOS counters. Verify that the RSET resistor value sets the desired charge pump current within the specified accuracy limits.

Part Context

The ADF4106 belongs to the ADF4106 family of integer-N synthesizers. It serves as a direct replacement for older models like the ADF4113, offering higher bandwidth and simplified architecture by removing the need for external frequency doublers in many high-frequency designs.
