It would be a more difficult problem if you needed to update the DAC in realtime. /tvb Hi Tom, one thing I noted in the PTTI paper on the CNS Clock II block diagram that was recently published here was that the CNS clock II is outputting a raw but sawtooth corrected version of the 1PPS. _ftp://ftp.cnssys.com/pub/PTTI/PTTI_2006.pdf_ (ftp://ftp.cnssys.com/pub/PTTI/PTTI_2006.pdf) This 1PPS will suffer from the jitter not recognized by TRAIM that we are talking about. I wonder why they did not use the OCXO output DIV 10E6 to generate a clean 1PPS, since this is so much more stable as you mentioned? Or is there a mistake in the block diagram? bye, Said _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
