Crystals? We don't need no stinking crystals! At least for the RTC. Chips like, e.g. the NXP iMX6, can use an internal ring oscillator in place of the customary 32kHz crystal to save even more on BOM cost and board space. Still needs a faster xtal for full operation, but low power mode and RTC can use the ring oscillator and keep the 24 MHz xtal powered down. _______________________________________________ time-nuts mailing list -- time-nuts@lists.febo.com -- To unsubscribe send an email to time-nuts-le...@lists.febo.com To unsubscribe, go to and follow the instructions there.
