ADF4150HVBCPZ

Overview

The ADF4150HVBCPZ is a fractional-N or integer-N frequency synthesizer featuring an integrated high-voltage charge pump. It operates with RF bandwidth up to 3.0 GHz and supports programmable divide-by-1, -2, -4, -8, or -16 outputs, enabling RF frequencies as low as 31.25 MHz. The device utilizes a 3-wire serial interface for register control. Power supplies include 3.0 V to 3.6 V for logic/analog sections and 6.0 V to 30.0 V for the charge pump. It includes analog and digital lock detect functions, an RF mute capability, and is housed in a 32-lead LFCSP package.

Feature Summary

• Integrated high-voltage charge pump supporting VP supply from 6 V to 30 V
• Fractional-N and Integer-N synthesis modes with programmable dual-modulus prescaler (4/5 or 8/9)
• Programmable output power levels ranging from -4 dBm to +5 dBm
• RF output mute function controllable via pin or software

Applications

• Wireless infrastructure systems
• Microwave point-to-point and point-to-multipoint radios
• VSAT radio equipment
• Test and measurement instruments
• Private land mobile radio applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified suppliers. Confirm the specific ordering suffix matches the required packaging format. Ensure compliance with RoHS directives and check for moisture sensitivity level requirements prior to soldering. Validate that the voltage ratings align with system design constraints.

Selection Notes

Select this component when direct drive of wideband VCOs is required without external operational amplifiers. Choose based on the need for high tuning voltages up to 29 V. Consider the available charge pump current settings and the specific RF input frequency range requirements. Evaluate the thermal resistance characteristics for the chosen PCB layout environment.

Part Context

This part belongs to the ADF4150HV series of high-performance PLL frequency synthesizers. It is designed to simplify designs by eliminating active filters, thereby improving phase noise performance compared to active topologies. The device integrates a third-order fractional interpolator and supports boost mode for fast locking times.
