GENERAL DESCRIPTION
The ADF4360-0 is a fully integrated integer-N synthesizer and
voltage controlled oscillator (VCO). The ADF4360-0 is designed
for a center frequency of 2600 MHz. In addition, a divide-by-2
option is available, whereby the user gets an RF output of be-
tween 1200 MHz and 1360 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.
