So this is for clock distribution in a studio? While our eras don't care about nano seconds or even micro seconds we do care that long of the same length have exactly the same number of samples. In other words at a given times into a track, all tracks have the same number of samples. I think what matters in this application is long term stability over days, weeks and even years. So the first step is always to figure out your requirements and USE NUMBERS. Next. It is not "either/or" you can put the PPL at 24..5MHz or 48K or you can divide by 10 and put the PPL at 2.45Mhz. or any place in between. One question: Why use the receiver as a clock source? Most use something independent like an OX or even Rb then use that to drive a DDS chip. -- Chris Albertson Redondo Beach, California _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
