The ADF4360-8 is an integrated integer-N synthesizer and
voltage-controlled oscillator (VCO). The ADF4360-8 center
frequency is set by external inductors. This allows a frequency
range of between 65 MHz to 400 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.
