FEATURES
Clock Generator PLL with Integrated VCO
GENERAL DESCRIPTION
The ADF4360-9 is an integrated integer-N synthesizer and
voltage-controlled oscillator (VCO). External inductors set the
ADF4360-9 center frequency. This allows a VCO frequency
range of between 65 MHz and 400 MHz.
An additional divider stage allows division of the VCO signal.
The CMOS level output is equivalent to the VCO signal divided
by the integer value between 2 and 31. This divided signal can
be further divided by 2, if desired.
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.
Primary output frequency range: 65 MHz to 400 MHz
Auxiliary divider from 2 to 31, output from 1.1 MHz to 200 MHz
