请问,如果我选择16MHz或40MHz作为S32K344的外部晶体振荡器,它们之间会有什么区别?它主要影响在哪里?在实际应用过程中,不同频率晶体振动对S32K344有什么影响?
Hi,
It does not have any meaning and the performance is guaranteed in entire range.
Of course, it is good to use the value which is used on our EVBs because RTD examples are oriented to this value. (makes staty of examples easier)
Moreover, if you decide to have direct clock frpm oscillator for CAN module, because of required clock precision, then the oscillator of required value must be used in dependence on used bitrate.
Selection can also depend on your experience with some type, frequency, EMI or anything....
Best regards,
Ladislav
