Overview
The ADF4360-3BCPZ from Analog Devices Inc. is a fully integrated integer-N synthesizer and voltage controlled oscillator (VCO). This device is designed for a center frequency of 1750 MHz, with an option to divide the output frequency by 2, resulting in an RF output range of 800 MHz to 975 MHz. The ADF4360-3BCPZ operates with a power supply ranging from 3.0 V to 3.6 V and features a simple 3-wire interface for controlling all on-chip registers. It also includes hardware and software power-down modes for energy efficiency. The device is packaged in a 24-lead Lead Frame Chip Scale Package (LFCSP).
