Thank you for all of your responses. So, are most of you saying that in my case, the 0.1uF is probably ok and to not bother purchasing 10pF caps for this
Something I realized is that when this appnote tells you what caps to use for decoupling, they don't specify a package. So, they might say "use a 22uF and
a 10pF", but they could be using through hole versions, while I'm using small SMT versions. My resonance will be entirely different from theirs (also
because of layout differences). The same would be true if they were using 1206 and I'm using 0805.
The bottom line for me is that the PLL is working great on our prototype with the 22uF and 0.1uF. We have 4 ground planes and there aren't any other
signals around the PLL. I seriously doubt it's worth the trouble and complication of adding a brand new part to the BOM just to satisfy an appnote that
happens to use different values.
Thanks for all of your help, it will come in handy in the future,
