Roger,

Thanks for the information.  That explains the lack of information on 
the web.

This manufacturer would not countenance manufacturing OCXOs operating on 5 V.  There is little technical information available,  I tried Trimble for info and was told that it was designed for a specific customer and that all the information was customer confidential - if I had paid a contractor a substantial sum to produce a specific design for me, I would not be happy if the manufacturer sent technical details to anyone who enquired!  I can therefore understand the policy and it does explain the shortage of technical information.
