Thanks for all the responses. A quick check before breakfast shows that
mine would seem to be for 5 Volts since the power consumption at that
input agrees with the data sheet referenced; the current peaks at 0.95 A
warming up and 0.13 A warm. Reference V out is 4.8 V.

Running it at 5V with a Ref out at 4.8V would seem too close. Maybe it's a
12V part?
If nothing else this could be a very stable, ovenized 4.8V lab reference
source..
Is anyone planning to monitor the aging/stability/noise of this reference?

Has anybody traced out the board? Is the power to the OCXO connected to one
of the power rails feeding the Rb?

A search of the Vectron site for OCO500 (which is on my unit) brings up
a datasheet which references that as a replaced unit.

I'm pretty sure it is a 5 Volt part Said, the power drawn in both states
matches the data sheet well. Warm up is quick and correct for the size
etc., at 5 V so

Indeed. He knows it well from my many visits, so I'm not all that worried.

This appears to be the datasheet - at least, it mentions OCO500 as
one the previous part numbers for this device.

I guess the best way to determine the operating voltage is by
monitoring the reference output and trying each supply voltage in turn
I'm getting a signal out with 3.3vDC in. I haven't tried to test this
higher.

Hi Dan
A couple of Ebay auctions for the Vectron OCO500-18 63.897600MHz OCXO as
a stand alone item, 190428236326 for example, link to a datasheet for the
C4550A2-0275.
Not sure how true or relevant that might be as a direct equivalent, but
the basic C4550 datasheet does quote OCO500
I'm getting a signal out with 3.3vDC in. I haven't tried to test this
higher.
The data sheet at
http://www.vectron.com/products/ocxo/c4550.pdf
shows 3 common input voltages. 3, 5, and 12 V.
It also says 3 W warmup. So I'd be tempted to see how much power it used as
