In this case how about making a super-simple GPSDO and just put the uncorrected 1pps directly into TMRO. The sawtooth jitter of an M12+ is 9 ns rms, which is just the magnitude you need to improve on the 20 ns single shot PIC-based TIC resolution. If you average long enough even hanging bridges will not be a concern. You'd have to do some work to get fancier, but it's hard to imagine a PIC-only GPSDO that would be simpler. /tvb _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
