My first thought was, "hell, using /two/ ceramic carriers for PCBs and using gold wires to connect them to eachother, that must have been a hell of an expensive DIL-14 oscillator". Then I looked at the Datasheet [1] (ok appnote) and guess what, that's no mere oscillator. That's a bona-fide OCXO. Vacuum packaged, nonetheless! Sure, it doesn't have the best stability compared to other OCXO, but compared to other DIL-14 sized OCXO, it's actually quite good. And it's only the size of a regular XO too! And this also explains the need for ceramic: an FR4 PCB would$ have too much outgasing that would then lead to drift. Lovely device! (Still think it's probably quite expensive) Attila Kinali [1] https://www.vectron.com/products/ocxo/EMXO-380-385.pdf -- The driving force behind research is the question: "Why?"
