GENERAL DESCRIPTION
The ADF4150HV is a 3.0 GHz, fractional-N or integer-N
frequency synthesizer with an integrated high voltage charge
pump. The synthesizer can be used to drive external wideband
VCOs directly, eliminating the need for operational amplifiers
to achieve higher tuning voltages. This simplifies design and
reduces cost while improving phase noise, in contrast to active
filter topologies, which tend to degrade phase noise compared
to passive filter topologies.
The VCO frequency can be divided by 1, 2, 4, 8, or 16 to allow
the user to generate RF output frequencies as low as 31.25 MHz.
For applications that require isolation, the RF output stage can be
muted. The mute function is both pin- and software-controllable.
A simple 3-wire interface controls all on-chip registers. The
charge pump operates from a power supply ranging from 6 V to
30 V, whereas the rest of the device operates from 3.0 V to 3.6 V.
The ADF4150HV can be powered down when not in use.
