How do those compare with vectron's part : ?

That part is interesting, but the phase noise (-124 dBc @ 100 Hz) isn't
particularly impressive compared to a middle of the road OCXO (-155dBc
at 100Hz)
The frequency stability is very nice, compared to a TCXO, and at a LOT
less power (40mW) than the OCXO (2W after warmup).
There's also this patent.

I don't really know if that's valid - it seems to propose something similar
to the numerically-compensated oscillator in my rather old PM6666 frequency
counter.
