MOTOROLA
SEMICONDUCTOR TECHNICAL DATA
PLL Frequency Synthesizer
Family
CMOS
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.
