GENERAL DESCRIPTION
The ADF4350 allows implementation of fractional-N or
integer-N phase-locked loop (PLL) frequency synthesizers
if used with an external loop filter and external reference
frequency.
The ADF4350 has an integrated voltage controlled oscillator
(VCO) with a fundamental output frequency ranging from
2200 MHz to 4400 MHz. In addition, divide-by-1/2/4/8 or 16
circuits allow the user to generate RF output frequencies as low
as 137.5 MHz. For applications that require isolation, the RF
output stage can be muted. The mute function is both pin- and
software-controllable. An auxiliary RF output is also available,
which can be powered down if not in use.
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.
