[time-nuts] Re: OCXO MV85A C20F-5V-SN spec or datasheet needed

[Matthias Welwarsky]

Hi Dave,

without seeing a picture of the OCXO, just going by the part number it is a 
Morion MV85 series OCXO. I've attached an ordering guide I found.

The ordering guide doesn't exactly match the nomenclature of the code you have 
posted, but:

C20F hints that the operating temperature range is -20°C to +70°C with 2e-8 
stability (relative to the nominal frequency I guess) and +-5e-8 per year.

It looks like it's a 5V part.

The MV85A parts are double-oven OCXOs, you find them all over Ebay or 
Aliexpress, but most of what you get is fake parts. 

Hth,
Matthias
