Overview
The ADF4360-4BCPZ is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO) designed by Analog Devices Inc. This device is centered around a frequency of 1600 MHz, with an optional divide-by-2 feature that allows for RF output frequencies between 725 MHz and 875 MHz. It operates with a power supply ranging from 3.0 V to 3.6 V and features 1.8 V logic compatibility. The synthesizer is controlled via a simple 3-wire serial interface and includes hardware and software power-down modes for energy efficiency.
