MOD54415 CPU Reference Clock
Posted: Fri Nov 06, 2015 7:10 am
Can someone verify that the "EXTAL" input pin of the MCF54418 CPU on the MOD54415 board is driven by a 25 MHz clock ??
(XTAL would, therefore, be open or not connected.)
Would it be possible to know the accuracy of that clock (e.g. 25 ppm ??).
Please note that I am not referring to the "RTC_EXTAL" input.
If information like that is written down somewhere, please let me know where. I tried to look at all the documentation I could find and searched the forum. I only found one 'sideways' reference to the "EXTAL" input, hence my guess that it is 25 MHz.
Thank you.
