The ADF4360-2 is designed for a center frequency of 2000 MHz. In addition, a divide-by-2 option is available, whereby the user gets an RF output of between 925 MHz and 1085 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.
