Said, Thanks for the clue on the Philips part. Sounds like a nice solution.
I just got a couple of sample parts from Maxim that I am going to play with (DS4000, MAX5121, and MAX6629). If they can do what Maxim claims it might be a fun experiment. I have one of those little TI MSP430 dev kits that I am going to try to use to run the show. We'll see.

They can even generate multiple outputs, say 1PPS, 10PPS, 100PPS etc all in paralell. On top of that, they can generate a software-selectable pulse-width, and can synchronize themselves to a GPS 1PPS input. Best of all, they are <<$2 in volume. For cheap eval boards, see: _http://www.sparkfun.com/commerce/product_info.php?products_id=667_ (http://www.sparkfun.com/commerce/product_info.php?products_id=667) That board can generate 5 independent pulse-outputs for $30. bye, Said _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts _______________________________________________ time-nuts mailing list time-nuts@febo.com https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
