A stupid side question: Why do have OCXO a Vref output in the
first place?
I can see that some form of reference might make stabilizing
the power in the crystal easier, but that still wouldn't make
it necessary to have an actual reference output.
And related to that: Would supplying the voltage reference
externally, in case of a broken Vref output, work for whatever
is inside that needs this reference voltage?
