Many thanks for the responses and ensuing discussion that has considerably value-added to the yes/no nature of my original question ;-) Now I know a lot more about primary/secondary standards than I did a (9,192,631,770 Cs wobbles * 86400) ago. I can now proceed with my unconventional calendar design (a cascade of dekatrons) knowing that it will be driven by an atomic ticker. BTW: does anyone know if a 0.55V p-t-p sine wave from an Rb source would be enough to clock an Atmel AVR microcontroller? The crystal/clock input *is* an amplifier, but didn't know if I'd need to do anything to the signal first, to get it closer to the 5V logic level.
