ADF4106BRUZ

Overview

The ADF4106BRUZ is a single-channel Integer-N PLL frequency synthesizer manufactured by Analog Devices Inc. It operates with an RF input frequency range of 500 MHz to 6 GHz and supports a maximum phase detector frequency of 104 MHz. The device functions on a 2.7 V to 3.3 V power supply, drawing a typical operating current of 9.0 mA at 3 V. It 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 voltage up to 5.5 V in 3 V systems. The component is housed in a 16-lead TSSOP package.

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 VP pin allows charge pump supply voltage up to 5.5 V for extended VCO tuning ranges.
• Supports both analog and digital lock detect modes via the MUXOUT pin.

Applications

• Local oscillators in wireless receiver and transmitter up-conversion/down-conversion sections
• Broadband wireless access systems
• Satellite communication systems
• Wireless LAN infrastructure

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and temperature grade. The BRUZ designation indicates surface mount installation in a TSSOP-16 package. Confirm that the required revision level matches the design specifications, as Analog Devices may update datasheets without notice.

Selection Notes

Select this component when a high-bandwidth PLL synthesizer is required for frequencies up to 6 GHz. Ensure the external loop filter and VCO are compatible with the programmable charge pump currents and the VP supply voltage limits. Verify that the reference input frequency falls within the 20 MHz to 300 MHz range and that the prescaler division ratio supports the desired output frequency spacing.

Part Context

The ADF4106 belongs to the ADF4106 family of frequency synthesizers from Analog Devices. It is designed to simplify system architecture by eliminating frequency doublers in high-frequency applications due to its wide bandwidth. The device integrates all necessary PLL components except for the external loop filter and VCO.
