Looking for specs: CTS Knights Oscillator

  1. Hello Group:
    I am looking for specs for a CTS Knights TCVCXO module.
    Part Number 970-3965-0
    Freq: 10.24 MHz

    Metal can is square, 2 inches on a side, 5/8 inches thick.

    Four pins: "Control", "Output", "Ground", "VS2".

    "8907" stenciled in the back: "7th week of 1989"??

    109K ohm resistance between VS2 and Ground. I think this
    is the resistance of the heater. But I don't want to connect
    it to 110 volts to see it if will draw 1mA.

    I tried 5v on control and vs2, no oscillation on output.

    I haven't found any specs on oscillators of this size/style.

    Any help would be appreciated.
    I got it at the surplus store for $3.50. There's more, if they're
    useful/valuable.

    Thanks.

    Ovens usually run at 12 or 24 V.

    When you get tired of looking at it not doing anything useful,
    try 12V and see how much current it draws. If none, try 24V.

    I did get tired of looking at it; even though it looks pretty nice since
    I polished the can to make it nice and minty!

    5v into Vs2 pin: 3.25 mA - No oscillation.
    12v - 12.83mA and it's oscillating!
    24v - 14.61mA and still oscillating.

    After an hour or so the case got a little warm, and the current went down
    a bit. I suppose it had gotten all warmed up.

    I realized the 10.24 MHz is a good frequency for the clock project I'm
    working on: 2^^10 * 10^^5.

    Cheers!
