Master Clock for your EtherREGEN

[alsterfan]

If someone is interested in a cheap alternative to the Chinese clock MartinT has started this thread with, here is what I use with great satisfaction:

Constant Temperatur Crystal OCXO 10Mhz 0.01PPM 2 Channel Output.

For me it has the advantage to only need 5v. So if there isn´t a LPSU 5v at hand, this clock can be powered with an USB output. At the moment I am using a power bank for that purpose after those flimsy cords (to be seen on 1 picture) have been replaced by a 2.5mm connector. Moreover there is no need to worry about BNC-cables. My external clock is attached to the ER with rigid BNC adaptors that I bought here:

Did you open up the clock and verify what brand and model is inside ?

 

No I didn´t the modification myself. However since I have ordered the same clock again which then will have to be modified too I might ask my friend to take a picture to show what is inside the tiny case.

As I mentioned before,"those flimsy cords (to be seen on 1 picture) have been replaced by a 2.5mm connector."

Hi Uwe,

 

Any ideal if sine or square wave ?

 

 

Sorry, I have no idea. Maybe there will be an indirect answer to your question, if the filter that John Swenson mentioned and that I am waiting for, will push SQ even more.

Hi Alster,

 

My understanding is that filter is only for sine wave clock and of no impact if square wave ... hence my query.

 

Cheers.

Yes I know, Richard, but although the technical data provided by the seller don´t have any information as to sine or square wave clock I decided to order the filter, which hopefully will be delivered within the next few days. I will share my experience with it thereafter.

Best,

Uwe
