ADF4150BCPZ

Overview

The ADF4150BCPZ is a Fractional-N/Integer-N PLL synthesizer from Analog Devices Inc. It operates with a power supply ranging from 3.0 V to 3.6 V and supports a maximum PFD frequency of 32 MHz in Integer-N mode. The device features a programmable dual-modulus prescaler (4/5 or 8/9) and an RF input frequency range up to 5.0 GHz. It includes a separate charge pump supply pin (VP) allowing extended tuning voltage up to 5.5 V. The output stage provides programmable power levels from -4 dBm to +5 dBm and can be muted via software or hardware control.

Feature Summary

• Supports both Fractional-N and Integer-N phase-locked loop configurations
• Programmable divide-by-1, -2, -4, -8, or -16 for the RF output buffer
• Integrated third-order fractional interpolator for cycle slip reduction
• Switched bandwidth fast-lock mode with selectable anti-backlash pulse width

Applications

• Wireless infrastructure including W-CDMA, TD-SCDMA, WiMax, GSM, PCS, DCS, and DECT
• Test equipment requiring precise frequency synthesis
• Clock generation systems
• Wireless LANs and CATV equipment

Procurement Notes

Verify the specific suffix 'BCPZ' against the manufacturer's ordering guide to confirm package type and temperature grade. Ensure the design accommodates the LFCSP-24 package dimensions and exposed paddle grounding requirements specified in the datasheet outline dimensions.

Selection Notes

Select this component when a combined fractional and integer-N synthesizer is required with integrated output dividers. Consider the VP pin requirement if the external VCO tuning voltage exceeds the AVDD supply level. Verify that the reference input frequency and sensitivity meet the system's clock source specifications.

Part Context

The ADF4150 is part of the ADF4150 series of PLL synthesizers. It is software compatible with the ADF4350 model. The device utilizes a 3-wire serial interface for register control and includes internal digital lock detect and analog lock detect functions for system monitoring.

Replacement Considerations

The ADF4350 is identified as a software-compatible alternative within the same product family.
