GENERAL DESCRIPTION
The ADF4360-4 is a fully integrated integer-N synthesizer and voltage-controlled oscillator (VCO). The ADF4360-4 is designed for a center frequency of 1600 MHz. In addition, a divide-by-2 option is available, whereby the user gets an RF output of between 725 MHz and 875 MHz.
Control of all the on-chip registers is through a simple 3-wire interface. The device operates with a power supply ranging from 3.0 V to 3.6 V and can be powered down when not in use.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. This device is a high performance RF integrated circuit with an ESD rating of <1 kV and it is ESD sensitive. Proper precautions should be taken for handling and assembly.
