GENERAL DESCRIPTION
The ADF4360-4 is a fully integrated integer-N synthesizer and
voltage-controlled oscillator (VCO). The ADF4360-4 is designed for
a center frequency of 1600 MHz. In addition, a divide-by-2 option
is available, whereby the user gets an RF output of between 725 MHz
and 875 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.

CIRCUIT DESCRIPTION REFERENCE INPUT SECTION
The reference input stage is shown in Figure 10. SW1 and SW2 are
normally closed switches. SW3 is normally open.When power-down is
initiated, SW3 is closed, and SW1 and SW2 are opened. This ensures
that there is no loading of the REFIN pin on power-down
