Overview
The ADF4360-5BCPZ 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 1300 MHz, with an optional divide-by-2 feature that allows for an RF output between 600 MHz and 700 MHz. It features a simple 3-wire interface for controlling all on-chip registers and operates with a power supply ranging from 3.0 V to 3.6 V. The device also includes power-down modes for energy efficiency when not in use.
