PLL Frequency Synthesizers

(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

TV Tuning

AM/FM Radios

Scanning Receivers

Two-Way Radios

Amateur Radio

OSC

CONTROL

LOGIC
