The so-called frequency synthesis means converting a certain reference frequency ^ into a series of new frequencies like fo1、fo.....fon. These new frequencies have the same stability as the former reference frequency. If we put a frequency splitter, whose splitting constant is fixed, between the 3-pin and 4-pin of CD4046, a new frequency doubler with the fixed multiple is formed. If we insert a multi-stage splitter with adjustable constants, then a multi-stage adjustable doubler is formed, which is the frequency synthesizer . In the figure is a frequency synthesizer made of CD4017.
