Frequency Generator	Frequency Synthesizer
It is simpler device than frequency synthesizer that generated signal with fixed parameter.	Frequency synthesizer is a complex system that uses frequency multipliers and dividers, mixers and bandpass filter to generate desired frequency.
A simple frequency generator usually has a tunable oscillator over a specified band meaning you can tune the frequency to any within the band	Frequency synthesizers cannot tune smoothly over a band, they only sit on the preset frequencies.
System is less stable	System is more stable
Contains high phase noise than synthesizer.	Contains lower phase noise than frequency generator.
Associated components are Oscillator, VCO, Modulator and Variable attenuation	Associated components are Mixers Multipliers, Dividers, Filters.
Frequency generator is mainly used in various embedded circuits as clock reference.	Frequency synthesizer is used for RF channel selections in various modem and rf transceivers.
