Good evening,
Studying the TIVA TM4C129x datasheet about using a single-ended 25-MHz oscillator on OSC0 instead of a 25-MHz crystal, I find this:
Table 27-51 is very simple. However, the title has this "a" exponent on it, and "a" above under table 27-50 tells to refer to Table 27-23 for additional MOSC requirements.
But Table 27-23 is this:
It has several parameters that aren't 100% clear to me which ones I should consider and which ones I should disregard when using a single-ended 25-MHz oscillator on OSC0. Some are clear, such as VIH, VIL, VHYS and DCOSC_EXT. The others aren't clear, specially since this table points back to table 27-51.
My questions are:
1) Which parameters from table 27-23 should I consider when using a single-ended 25-MHz oscillator on OSC0?
2) Selecting a 25-MHz crystal for this MCU is very complicated if trying to go outside the recommended ones from the datasheet, which most are today unavailable. However, can I assume that selecting an external crystal oscillator to use as a single-ended 25-MHz oscillator on OSC0 is much simpler, needing to only consider table 27-51 and the parameters from question 1 above of table 27-23?
Thanks for your help
