Hello OMs,
has someone already tried a LNB mod with a MCXO like this one?

Looks interesting, stable like a OCXO but current consumption likeTCXO.

Yes, I documented here the Si Time 0.1ppm fitted inside my LNB
Hi Dave,
what is your impression with this MCXO stabilisation?
Does it work so good like it sounds according to the datasheets?
I can't find any posts from you about that here in this forum.

Dave could it be that the "Si Time 0.1ppm" are normal TCXOs?
https://www.mouser.de/datashee…7-datasheet_1-1371858.pdf
I see 0,1 / 0,25ppm on their datasheets.
The MCXOs are described with 0,02 / 0,03ppm stability.

OK Dave,
but those SiTime MEMS TCXOs are not the same as the MCXOs i mean
even if the name M-CXO could be understood as MEMS TCXO.
You can see on the datasheet that the stability is much better.
So i guess till now nobody has tried a mod with a "real" MCXO.

I think this is a syntax issue ?
BTW how much are they ?
73's Dave
see here: https://de.farnell.com/search?st=MCXO
About 50€ but unfortunately a suitable frequency (25/27) MHz is not in the list.
But the technical data looks very impressive.

Those are less accurate than the one I proposed ?

Look at the first datasheet i posted.

I was looking at above as requested. I'll leave this thread as it's going nowhere.
So nobody has used a MCXO till now..
I haven't . . .
maybe because the price difference to a cheap GPSDO is not very big....

Or maybe no one knows how much it is anyway, let alone how to buy one ?
