Yes, exactly. But the CSAC is marketed for a small niche, both given its
price and that at least until fairly recently they couldn't (and I'm
assuming still today can't) make that many.
Small like (or smaller than) an OCXO, but with better stability and much
lower power use. For a higher price. If one plotted ADEV/W I recon it
would turn out a great performer. ADEV/USD and it wouldn't fare as well.
I did go as far as asking for a quote from a Symmetricom rep. last year
with a wrist watch project in mind. Put that project on the shelf when I
got the quote back.:) Great to see someone with deeper pockets and more
dedication made it happen! Is there any competition/alternatives for a
pocketable time-nutty-stable movement?
