Doesn't sound too good I'm afraid... in addition to the shipping issues, I
wonder if it was the right decision to use this OCXO...
Are there any low phase noise OCXO available (preferably from stock)

Daniel, I suggest a MTI 260 OCXO or an Oscilloquartz 8663.

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 (
It is AC coupled. In fact, many of these units have a bad capacitor and a very
low output. If you get one like that, you will need to open the can and replace
the SMT capacitor.
I believe it is designed to drive a 50 ohm load but I do not know what effect
that will have on the phase noise.
One thing to be aware of on the MV89 is that it is a 5 MHz osc that uses a
freq doubler.
On the ones I've tested, without further filtering, every other cycle's
period is different by ~ 1 ns or so.
For a time nut that likes to see 1ps jitter, it is a whole lot of cycle to
cycle edge jitter
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.

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
Hi

The only time you can get fairly good parts is when the first hit the market.
