That is a fair point. The result would be high jitter. Still worth a go though, since an inverter is cheap (and one might be needed anyway for level conversion purposes). If the device does not provide a programmable offset, that is (as Mike Cook suggested). _______________________________________________ questions mailing list questions@lists.ntp.org http://lists.ntp.org/listinfo/questions
