GENERAL DESCRIPTION
The ADF4360-7 is an integrated integer-N synthesizer and
voltage controlled oscillator (VCO). The ADF4360-7 center
frequency is set by external inductors. This allows a frequency
range of between 350 MHz to 1800 MHz. In addition, a divide-
by-2 option is available, whereby the user receives an RF output
of between 175 MHz and 900 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.
