Frequency multiplication tends to increase jitter as well as

Very interesting, Mike. By "jitter" do you mean phase noise?

No. Jitter is jitter is jitter, but is related to phase noise that is phase
noise that is phase noise.

Thanks,

Generally speaking. it is the part of the blank which is directly under the
electrodes, and very near to the edges of the electrodes, that determine the
frequency. I was close to some 135 MHz crystal filter some years ago, but
wasn not aware of the technology useed -- it wasn't used in the final
design.
