Overview
The ADF4360-1BCP 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 2250 MHz, with an optional divide-by-2 feature that allows for an RF output range of 1025 MHz to 1225 MHz. The ADF4360-1 is controlled via a simple 3-wire interface and operates with a power supply ranging from 3.0 V to 3.6 V. It also features power-down modes to conserve energy when not in use.
