200MHz crystal for crystal filter?

Your link is to something called a crystal filter. It does not appear to be the same as a crystal. It probably will not work in an oscillator circuit.

To generate high MHz waveforms, it is common to use a lower Hz crystal in an oscillator, and then to detect one of the harmonics with a narrow bandpass filter, and use that.

The article at this link has some information.

At this frequency you're probably getting into non-quartz
resonators - SAW or BAW filters - if you're looking for a
passive solution.

Yes this is true, I search crystal for construct 200MHz crystal filter with low ERS. Profi crystal filter from nicks.com use crystal on 5th overtone.
