oscillator designing problem

[ali kotb]

hello

iam designing a crystal osc. with some sort of filtering the fundamental to work on the overtones
how to ensure that the oscillation produced is crystal slaved (produced by crystal itself not the filter (it contains many +ve fb branches that do oscillate ) )?
i got the needed freq with crystal and without crystal so that means that the osc. wasn't crystal slaved

plz help me
