This document covers various methods but I agree with Rick about phase
locking a separate crystal oscillator; harmonic frequency
multiplication is more useful at higher frequencies where other
methods are unavailable:
An alternative very simple design I might try is a variation of the
active frequency multiplier where the 5th harmonic is filtered
directly from the output of the digital divide by two stage.
