[time-nuts] Re: info on Tele Quarz Group 5 MHz oscillator?

[Germán Herrera]

Hi
I've a similarly sized oscilloquartz with a pin configuration similar 
with yours.
Attached are a couple pictures with the pin functions annotated. Supply 
voltage is 12Vcc (DC-DC converter is on the same board).

Hope it helps.
