ADF4106BRU-REEL

Overview

The ADF4106BRUZ-RL is a single-channel integer-N PLL frequency synthesizer from Analog Devices, designed for local oscillator implementation in RF up-conversion and down-conversion sections. It integrates a low-noise digital phase frequency detector, precision charge pump, programmable reference divider, A/B counters, and a dual-modulus prescaler. The device supports an RF input frequency range of 500 MHz to 6.0 GHz with a normalized phase noise floor of -223 dBc/Hz. It operates on a 2.7 V to 3.3 V supply, drawing approximately 9.0 mA to 10.5 mA depending on conditions. The component is housed in a 16-lead TSSOP package and functions within an industrial temperature range of -40°C to +85°C.

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 via RSET
• 3-wire serial interface with analog and digital lock detect capabilities
• Hardware and software power-down modes reducing current to ~10 µA

Applications

• Broadband wireless access systems
• Satellite communication equipment
• Wireless LAN infrastructure
• Base stations for wireless radios
• Instrumentation and signal generators

Procurement Notes

Verify the specific suffix 'RL' indicates tape and reel packaging when sourcing. Confirm the 'B' version designation corresponds to the -40°C to +85°C industrial temperature range. Ensure compatibility with the EV-ADF4106SD1Z evaluation board if development support is required. Check for RoHS compliance status as indicated by the manufacturer's ordering guide.

Selection Notes

Select this component for applications requiring high-frequency synthesis up to 6 GHz with low phase noise. The separate VP pin allows extended tuning voltage up to 5.5 V even with a 3 V system supply. Ensure the external VCO and loop filter are compatible with the programmable charge pump characteristics. Verify that the required division ratios fit within the A and B counter limits.

Part Context

The ADF4106 is part of the ADF41xx family of PLL frequency synthesizers. It serves as a successor to earlier models like the ADF4113, offering higher bandwidth and improved noise performance. The BRUZ variant specifically denotes the 16-lead TSSOP surface-mount package option, distinguishing it from the LFCSP package variants available in the same product line.
