Ok... maybe i´ll make a not so smart question but... if the MV89 is bad,
what´s the recomended parts from ebay for something like that? (10MHz
OCXO to upgrade some sort of equipment)
(I´m asking because I did almost the same thing than our friend Hagar...
I noticed that the MV89 wasn´t as good as I would like it to be).

Hi
You would want a 50 ohm load on the output of the OCXO. Based on recent
experience, you may have to buy 10 or more before you find one that is
reasonably close to working correctly. The low output issues are far from the
only problem on these units.

Hello there,
I'm trying to build a low phase noise signal generator with a Morion MV89 OCXO.
( http://www.morion.com.ru/catalog_pdf/MV89-OCXO.pdf )
The 10 MHz Sine coming from the MV89 shall be converted to a 10 MHz rectangle
with the LTC6957-3 ( http://cds.linear.com/docs/en/datasheet/6957f.pdf ).
Since the information in the MV89's data sheet is rather thin and shipping is
taking a lot longer than expected/promised, I thought I'd ask if someone here
has any experience with it and maybe can answer some questions I have...
1. Does anyone know if the MV89 is internally AC coupled / if the Output Sine
has an Offset?
2. I'm not sure if termination is needed in this case or which way to terminate
would be best for a low phase noise/low jitter application. Can anyone give me
some hints to what would be important?
Thanks a lot!
