Correct. But at $2+/- each it's easy to use one uC for a divider and another uC for the GPSDO algorithm. Yet another for an IRIG option; perhaps another for NTP. I think I remember RickH saying that his CNS II clocks use up to 5 microprocessors. /tvb _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
