Electronic – Is this a crystal oscillator

identificationoscillatorpackages

I've never encountered anything in this package. Is it a crystal oscillator? What are the six pins used for? Would it potentially be ovenized?

All I know is that the manufacturer is Kyocera. Any help greatly appreciated!

Markings: Kyocera 7M37 012C M1

Logic chips, DIP-8 oscillator, and HC-49/U resonator are included for size reference. The circular things in the middle are the mystery devices of interest. I did not clip off two of the leads – they're all like that.

enter image description here I have recently acquired some of these myself and was searching for info which landed me here. I was able to solve more of this mystery on my own. By orienting the tab on the can to be pin number one following the traditional DIP design. Using pin 3 as +5V and pin 4 as the ground I was able to obtain a surprising and desirable output. Four outputs exactly. Included is my not so professional schematic . The quiescent current is a low 1.25ma so i am confident that my efforts have amounted to something. With four stable outputs at different frequency's this device truly has much potential on the bench and with a few discreet components one can produce many different wave forms. I am sure this device has more secrets as well. It took some effort but I am glad to help others and myself.
