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 Parameter NAC1 CSAC Aging 3E-10/mo 9E-10 1E-9/yr 10E-9 ADEV 2E-11 @ 100sec 2.5E-11 8E-11 @ 10 8E-11 2E-10 @ 1 sec 2.5E-10 phase noise -86 @ 10 -70 -120 @ 100 -113 -138 @ 1000 -128 -143 @ 10k -135 -148 @ 100k -140 -150 floor max chg 1E-9 (-20 to 65) 5E-10 (-10 to 35) pwr 1.2W op 0.12 1.8W warm 0.14

Jim am I reading the casc power consumption correctly? .12 and .14 W. Thats 10X lower.

Hi Yes the numbers are correct, the NAC pulls roughly 10X the power of a CSAC.

Hi If you set them both on the table, the CSAC’s I’ve seen are just slightly smaller than the NAC’s. It’s not by much. I never bothered to see if the mechanical specs on the parts reflected this or not.
