It's a clever idea: they observe that most commodity computer motherboards have temperature sensors onboard, and found a correlation between clock frequency and the output of that temperature sensor. Using that model they were able to build a "pure software TCXO" that maintains frequency an order of magnitude better than the typical performance of a crystal without the corrections. _______________________________________________ time-nuts mailing list -- [email protected] -- To unsubscribe send an email to [email protected] To unsubscribe, go to and follow the instructions there.
