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 TV Tuning
AM/FM Radios Scanning Receivers
Two-Way Radios Amateur Radio
