Hi Attila,

 Unfortunately, since they redesigned their webpages, i cannot find the
OCXOs listed anywhere anymore (only the 8607 shows up).
Oscilloquartz has discontinued their OCXO line. The only exception is the
BVA OCXO.

Best regards

Oh..kay?
Did Oscilloquartz at least sell their OCXO business to someone else?
Or did they just close it? (I googled, but didn't get any results)

This is not as drastic as it sounds. In practice have many parts of the
Oscilloquartz oscillators been built my MicroCrystal and then sold by
Oscilloquartz as one part-number and MicroCrystal by another part-number.

Unfortunatly I havven't found the 8663 and similar pop up on
MicroCrystal's site.

Usually new OCXOs from distributors are expensive parts (low noise
being a premium feature)... if you have to use them professionally OK
otherwise you have no other way than the usual auction site.

Re: [time-nuts] Morion MV89 and LTC6957

2013-11-06 Thread TMiller
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.

Re: [time-nuts] Morion MV89 and LTC6957

2013-11-06 Thread WarrenS


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 that shows up on any signal that is divided down by a non 
2 to n divider.
The second thing I've seen is that the output Cap is open in a large number 
of them.

 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!
