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.
