Overview
The ADF4360-4BCPZRL is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO) designed by Analog Devices Inc. This device is optimized for a center frequency of 1600 MHz, with an optional divide-by-2 feature that allows for RF output frequencies between 725 MHz and 875 MHz. It features a simple 3-wire interface for controlling all on-chip registers and operates with a power supply range of 3.0 V to 3.6 V. The ADF4360-4BCPZRL also includes power-down modes for energy efficiency when not in use.
