ADF4152HVBCPZ

Overview

The ADF4152HVBCPZ is a high voltage fractional-N or integer-N frequency synthesizer with an integrated charge pump. It supports RF input frequencies up to 5.0 GHz and operates on a 3.0 V to 3.6 V supply, while the charge pump utilizes a separate 6.0 V to 30 V supply (VP). The device features a programmable output divider allowing frequencies as low as 31.25 MHz, a 3-wire serial interface, and analog/digital lock detect functions. It is housed in a 32-lead LFCSP package.

Feature Summary

• Fractional-N and Integer-N PLL synthesis with RF bandwidth up to 5.0 GHz
• Integrated high voltage charge pump supporting VP from 6.0 V to 30 V
• Programmable output dividers (÷1, ÷2, ÷4, ÷8, ÷16) for flexible frequency generation
• RF output mute function controllable via pin or software

Applications

• Wireless infrastructure systems
• Microwave point-to-point and point-to-multipoint radios
• Very small aperture terminal (VSAT) radios
• Test equipment applications

Procurement Notes

Verify component authenticity through authorized Analog Devices distributors. Confirm the specific BC suffix indicates the lead-free LFCSP-32 packaging variant. Ensure environmental compliance documentation matches project requirements prior to procurement.

Selection Notes

Select this model when external tuning voltages exceed standard logic levels, requiring the integrated high voltage charge pump. Verify that the required RF input frequency falls within the 0.5 GHz to 5.0 GHz range. Ensure the system design accommodates the separate VP power supply rail for the charge pump operation.

Part Context

This component belongs to the ADF4152HV series of high voltage PLL synthesizers. It is designed to drive external wideband voltage-controlled oscillators directly, eliminating the need for operational amplifiers in the loop filter path. This integration simplifies circuit design and reduces overall system cost.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Evaluate alternative models based on matching RF bandwidth, charge pump voltage capabilities, and package compatibility.
