OCXO is it Vectron International ?

(1/1)

Hi,

Hamfest find labeled as follows:

VI QK O.30.00801
EO 0374.8037
10 Mhz +12V
2799 8075291/028

On the back

01203

Device looks like this -

Top
1 2 3
|    |
|    |
|    |
|    |
4   5

Pin 4 is case/ground. As near as I can tell pin 3 is 12V+.

Am I correct that this is a Vectron International OCXO?

Does anyone have a datasheet?  No reply from Vectron and nothing on the web on this device.

Thanks,

Marc

Hi

It was designed in the old Quartzkeramik plant outside Munich in the 1990's. When that plant shut down, the design and production moved to the old KVG plant (then part of Vectron). Based on the date code (late 1999) it could have come from either plant. KVG is back to being independent again so who knows where the information on that unit might be. After nearly 20 years ... hard to guess.

Since it is a standard pinout and you know the supply voltage ... just hook it up and see what happens. If it has an EFC, you can work out the range from the point that it gets to center frequency.

Bob,

Thanks.

Will take me a bit to get the time to try it out, but I'll repost here when I do.

From KVG -

Hi,
please see attached the datasheet of the OCXO.
The pin configuration is as follows:
1 – RF output
2 – Ground
3 – Frequency adjustment Vc
4 – Reference voltage output (for internal use)
5 – Supply voltage
 
BTW: Bob’s comments in the blog you mention are correct. The part was manufactured at Quarzkeramik nearby Munich in 1999 or 2000.

Oh and it did work, sounded like dirty square wave on shortwave...scope as time permits.
