Cybershaft rubidium clock...low priced option?

Not sure what happened to John's post as it's blank but very well said.

 

Yeah, something odd has been going on today with the mobile app. I saw a bunch of blank posts (just the poster's name) in some other threads. But via a web browser they are visible.

Hahaha! Made me laugh. Trying to achieve low phase noise and then using a plug in XO... Also, does not the 575 achieve lower phase noise than the 950 at 100 MHz... At least that is what I see in published Crystek specs...

 

And actually, current production CCHD-575s, are well outperforming Crystal's own web published measurements. They sent us 3 samples of a mid-20s MHz rate, and they came with 3 individualized graphs--with 10Hz offset noise at -108, -110, and -112. I called and asked if those were hand picked and they said no, that they have just improved their process a great deal. Even Crystek's Sales Director could not give me a reason--other than ruggedness and installed clientele for the form factor--for the continuation of the 3 times the price CCHD-957 series.

(But I think Barrows knows all this already. )
