Something rated for gigabit ethernet by definition has to be dealing with ~1 nanosecond pulses without adding a significant amount of skew or latency amongst the 4 pairs, or else it would mess up the network traffic passing through it. A PPS signal ought to do just fine... -- -Chuck _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
