This data sheet introduces the features of the ADF4360-3 integrated synthesizer and VCO
The ADF4360-3 is a fully integrated integer‑N synthesizer and voltage‑controlled oscillator (VCO) designed for a center frequency of 1750 MHz with an output range of 1600 MHz to 1950 MHz (divide‑by‑2 option yields 800 MHz‑975 MHz). It operates from a 3.0 V‑3.6 V analog supply, uses 1.8 V logic levels, and is controlled via a simple 3‑wire serial interface.
The document provides detailed specifications, timing characteristics, absolute maximum ratings, pin configuration and function descriptions, typical performance curves, application examples, PCB design guidelines, and an ordering guide for the ADF4360-3 device.

The device provides an output frequency range of 1600 MHz to 1950 MHz, with a divide‑by‑2 option giving 800 MHz to 975 MHz.
It operates from a 3.0 V to 3.6 V analog power supply and uses a 1.8 V logic supply.
All on‑chip registers are accessed through a simple 3‑wire serial interface.
The analog supply (AVpp) may be between –0.3 V and +3.9 V relative to ground.
