I found a canned oscillator hanging around my desk. It is a TCXO or even VC-TCXO marked Motorola K1516AE 1813-0535 10000000 Hz. No pinout. I haven't found a datasheet online, or I used the wrong search keywords.
On the other hand with some keywords I get directed to an eBay item of a replacement board for an HP spectrum analyzer, the HP 8562A. Usually old manuals show the schematic diagram and luckily the whole PDF is available on Keysight website. It is 462 pages long with only block diagrams. But I was VERY lucky since at page 6-25 (217 in the PDF), figure 6-7, in a "manual change" section the oscillator diagram is shown in clear! And the K1516AA TCXO pinout is there!

I have a K1516AE but I think the pinout shown for K1516AA will not be too far away.
