in AN3262 a PLL Filter Calculator is described, but in reality it is for 9S12 an cannot be used for the far faster S12X Family,
Is there an apnote using the PLL Filter with the 9S12X family?
Thank you Edward,
In the calculators window here are the terms “stability factor” and “damping factor”.
As I found no appnote or document for the calculator, may you explain these terms to me?

Stability =50 and damping factor =0.9, I think are things, mentioned XDP512 RM
A.5.3.1 XFC Component Selection
The loop bandwidth fC should be chosen to fulfill the Gardner’s stability criteria by at least a factor of 10, typical values are 50. z = 0.9 ensures a good transient response.
I used default 50 and 0.9 for years without any problems. If I had problems with stability or too slow PLL locking, I would study it deeper/
