PLL Frequency Synthesizer
Family
CMOS
The devices described in this document are typically used as low–power,
phase–locked loop frequency synthesizers. When combined with an external
low–pass filter and voltage–controlled oscillator, these devices can provide all
the remaining functions for a PLL frequency synthesizer operating up to the
device’s frequency limit. For higher VCO frequency operation, a down mixer or
a prescaler can be used between the VCO and the synthesizer IC.
These frequency synthesizer chips can be found in the following and other
applications:
CATV
AM/FM Radios
Two–Way Radios
TV Tuning
Scanning Receivers
Amateur Radio
OSC
