GENERAL DESCRIPTION

The ADF4360-2 is a fully integrated integer-N

synthesizer and voltage controlled oscillator (VCO). The

ADF4360-2 is designed for a center frequency of

2000MHz. In addition, there is a divide-by-2 option

available, whereby the user gets an RF output of between

900MHz and 1075MHz.

Control of all the on-chip registers is via a simple 3-wire

interface. The device operates with a power supply rang-

ing from 3.0V to 3.6V and can be powered down when not

in use.
