By far the easiest solution would be to discipline the 100MHz OCXO directly to the PPS - this will have negligible impact on the OCXO's phase noise and is a simple, reliable method - the Luis Cupido design will work very well for example, and there are other designs. regards Grant _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
