ADF4360-7BCPZ

Overview

The ADF4360-7 is an integrated integer-N synthesizer and voltage-controlled oscillator (VCO) from Analog Devices. It operates within a frequency range of 350 MHz to 1800 MHz, with a divide-by-2 option providing 175 MHz to 900 MHz. The device utilizes external inductors for center frequency setting and features a programmable dual-modulus prescaler (8/9, 16/17). It supports a 3-wire serial interface, 1.8 V logic compatibility, and operates on a 3.0 V to 3.6 V power supply. Key electrical specifications include a typical phase noise of -116 dBc/Hz at 100 kHz offset and output power levels programmable from -14 dBm to -5 dBm.

Feature Summary

• Integrated Integer-N Synthesizer and VCO with 350 MHz to 1800 MHz output range

• 3-Wire Serial Interface with 1.8 V Logic Compatibility
• Programmable Output Power Levels (-14 dBm to -5 dBm) and VCO Core Current

Applications

• Wireless handsets (DECT, GSM, PCS, DCS, WCDMA)
• Test equipment
• Wireless LANs
• CATV equipment

Procurement Notes

Verify the specific suffix against the manufacturer's ordering guide to confirm package type and tape/reel specifications. Ensure that the external inductance values selected align with the desired frequency band, as the device relies on external components for frequency determination. Confirm power supply decoupling requirements for AVDD, DVDD, and VVCO pins during design review.

Selection Notes

Select external inductors based on the target frequency range, noting that values greater than 3.3 nH require a parallel 470 Ω resistor. Choose the appropriate dual-modulus prescaler setting (8/9 vs. 16/17) based on the minimum required division ratio for contiguous frequency coverage. Ensure the reference input frequency falls within the 10 MHz to 250 MHz range and matches the CMOS input sensitivity requirements.

Part Context

The ADF4360-7 belongs to the ADF4360 family of RF synthesizers. It shares architectural similarities with other models in the series but is distinct in its specific frequency coverage and internal prescaler options. Evaluation boards such as the EV-ADF4360-7EB1Z are available for performance verification. The device is designed for applications requiring low phase noise and flexible frequency generation in compact form factors.

Replacement Considerations

Publicly confirmed substitute part numbers are not provided in the source documentation. Designers should consult the manufacturer's current product selection guide for cross-references or updated model replacements.
