ADF4360-7BCPZRL7

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 extending the output down to 175 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 parameters include a typical phase noise of -116 dBc/Hz at 100 kHz offset and a charge pump current ranging from 0.312 mA to 2.5 mA.

Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the B version grade matches the required temperature and performance specifications. Ensure the ordering part number aligns with the Rev F datasheet documentation provided by Analog Devices.

Selection Notes

Select external inductors carefully to set the desired VCO center frequency, noting that values greater than 3.3 nH require a parallel 470 Ω resistor. Choose the appropriate dual-modulus prescaler setting based on the target frequency to ensure contiguous coverage. Program the charge pump current via RSET to optimize loop bandwidth and phase noise performance.

Part Context

The ADF4360-7 belongs to the ADF4360 family of integrated synthesizers. It is designed for applications requiring precise frequency generation with low phase noise. The device integrates the VCO core, phase detector, charge pump, and counters into a single chip, reducing component count in RF designs.

Replacement Considerations

Check for other variants in the ADF4360 family (e.g., ADF4360-0 through ADF4360-9) which cover different frequency ranges. Ensure pin compatibility and register configuration are identical before substituting with other models in the series.
