I grew up in an industry where we called everything that was way overspec'ed, platinum-iridium xxx. I think there is a broad interest in e.g. low-tempco engineering or low-noise regulators and having some in the pocket designs that start with jellybean discrete parts and occasional hi-spec parts

Hi Separate from the analysis of the voltage on the OCXO, there is another part to this: Ok, so why am I harping on the “need” for all this from a system standpoint ? 1) Adding stuff to a design that does not make it measurably better is simply a waste of money. That’s ok if it’s your money.
