The ADF4360-3 is a fully integrated integer-N synthesizer and
voltage controlled oscillator (VCO). The ADF4360-3 is de-
signed for a center frequency of 1750 MHz. In addition, there is
a divide-by-2 option available, whereby the user gets an RF out-
put of between 800 MHz and 975 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.
