> The challenge seems to me to be how to temperature stabilize the entire DAC chain without putting it all in an oven
Hi Forrest, Generally you don't have to temperature stabilize the DAC because it is inside the phase-locked control loop and the loop will adjust for temperature dependencies, just as it adjusts for drift and temperature dependencies in the oscillator. You will want your phase detector to be reasonably temperature stable however. In the time-nuts archives you will find posts from Lars Walenius and myself with schematics and code for Arduino-based GPSDOs which you might want to study. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
