ADF4360-9BCPZ

Overview

The ADF4360-9BCPZ is an integrated integer-N synthesizer and voltage-controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within a primary output frequency range of 65 MHz to 400 MHz, determined by external inductors connected to pins L1 and L2. The device supports a 3-wire serial interface for register control and functions with a power supply ranging from 3.0 V to 3.6 V. Key electrical specifications include a typical phase noise of -91 dBc/Hz at a 10 kHz offset and a programmable RF output power level adjustable in 3 dB steps from -9 dBm to 0 dBm. An auxiliary divider stage allows the VCO signal to be divided by integers between 2 and 31.

Feature Summary

• Integrated integer-N synthesizer and VCO with a frequency range of 65 MHz to 400 MHz
• Programmable RF output power levels: -9 dBm, -6 dBm, -3 dBm, and 0 dBm
• Auxiliary divider stage providing outputs from 1.1 MHz to 200 MHz
• Digital lock detect and software power-down mode capabilities

Applications

• System clock generation
• Test equipment
• Wireless LANs
• CATV equipment

Procurement Notes

Verify the specific suffix BCPZ against the manufacturer's ordering guide to confirm package type and tape/reel configuration. Ensure that the required external components, specifically the inductors for L1/L2 and the RSET resistor for charge pump current setting, are sourced separately as they are not included in the package.

Selection Notes

Select this component when a low-frequency synthesizer up to 400 MHz is required. Designers must calculate the appropriate external inductor values to set the desired center frequency and ensure the reference input sensitivity matches the available clock source. Consider the 1.8 V logic compatibility if interfacing with lower voltage microcontrollers.

Part Context

This part belongs to the ADF4360 family of frequency synthesizers. While other variants in the series cover higher frequency bands such as 2.4 GHz or 1.6 GHz, the ADF4360-9 is specifically optimized for applications requiring frequencies below 400 MHz. It shares the same core architecture and control interface as its higher-frequency counterparts.

Replacement Considerations

Direct replacements within the same family include the ADF4360-0, ADF4360-3, ADF4360-4, ADF4360-5, and ADF4360-9. Selection depends on matching the required output frequency range. Verify pinout compatibility and inductor requirements when substituting.
