What you are looking for is here: You could put a switch-selected digital divider between the VCO and phase detector so that the VCO is an exact multiple of the crystal oscillator’s frequency.


Posted August 21, A frequency-synthesiser’s VCO jumps abruptly only to pre-determined frequencies, a VCO with a variable DC control voltage smoothly glides to any frequency within its range.
