I have an application using the DA14585 that is subject to extreme EMI. I believe that this is disturbing the high frequency oscillator and causing the microcontroller to not run or constantly reset in situations. Would it be possible to replace the 16MHz crystal with a MEMS oscillator to improve this?
The data sheet only lists a minimum and typical external clock voltage of 1 and 1.2V, respectively, but no maximum voltage. Would this oscillator work?
