Jim am I reading the casc power consumption correctly? .12 and .14 W.
Thats 10X lower.
Yes..
Any idea on the $$

CSAC in the several kilobuck range, NAC in the 10-20k range, I think.

They're about the same size.. NAC is slightly smaller, I think.

Here's a quick summary of the datasheet performance between the
Vectron/Accubeat NAC1 and the MicroSemi CSAC.  Bear in mind that Microsemi
now has a wider temp range (i'm using the old rev J datasheet)

CSAC is 1/10th the power
NAC1 has a better crystal, so the phase noise is better
the "atomic" part is comparable in performane
