ADF4360-7BCPZRL

Overview

The ADF4360-7 is an integrated integer-N synthesizer and voltage controlled oscillator (VCO) manufactured by Analog Devices Inc. It operates within a frequency range of 350 MHz to 1800 MHz, with a divide-by-2 option providing outputs between 175 MHz and 900 MHz. The device functions on a 3.0 V to 3.6 V power supply and features a 3-wire serial interface for register control. Key electrical specifications include a typical phase noise of -116 dBc/Hz at a 100 kHz offset and a programmable output power level ranging from -14 dBm to -5 dBm. The center frequency is determined by external inductors connected to the L1 and L2 pins.

Feature Summary

• Integrated Integer-N Synthesizer and VCO with a frequency range of 350 MHz to 1800 MHz
• Programmable dual-modulus prescaler supporting 8/9, 16/17, or 32/33 configurations
• Adjustable output power levels from -14 dBm to -5 dBm via current programming
• Low power sleep mode consuming approximately 7 µA

Applications

• Wireless handsets including DECT, GSM, PCS, DCS, and WCDMA systems
• Test equipment requiring stable local oscillators
• Wireless LANs (WLAN)
• CATV equipment

Procurement Notes

Verify that the specific part number matches the required frequency band and package type. Confirm that the ordering suffix corresponds to the intended reel or tray packaging configuration as defined in the manufacturer's ordering guide. Ensure compatibility with the 3-wire serial interface logic levels before integration.

Selection Notes

Select the appropriate external inductance values for the L1 and L2 pins to achieve the desired center frequency, noting that resistors may be required in parallel for inductances greater than 3.3 nH. Choose the prescaler division ratio based on the target VCO frequency to ensure valid counter operation. Consider the charge pump current setting relative to the loop filter design for optimal lock time and phase noise performance.

Part Context

The ADF4360-7 belongs to the ADF4360 family of frequency synthesizers. It shares architectural similarities with other variants in the series but is distinctively tuned for the 350 MHz to 1800 MHz output range. The device utilizes a silicon bipolar-CMOS process and includes internal band select logic to manage VCO tuning across its wide frequency span.

Replacement Considerations

Direct replacements within the same family include the ADF4360-0 through ADF4360-9 variants, which cover different frequency bands. When substituting, verify that the new variant's frequency range encompasses the required application spectrum and that the pinout remains compatible with the existing PCB layout.
