Hello,

The new errata item SSWF021#45, PLL Fails to Start, includes the following:

"On rare occasions the PLL does not start properly."

Could you define "rare"?

Thanks, Charlie Johnston

We are trying to get a good handle on the expected fail rate. Best I can give you at this time is that on those parts it is on the order of 100 parts per million that have the potential to show this fail mechanism.

Thanks, Bob.
Where will I find the info when it's available? This thread? The next Errata revision?

If there is a significant change it will probably be noted in the application note referenced by the errata document.

Hi Bob,
How does "100 parts per million" relate to FIT as described in the Safety Analysis Report Summary?
Thanks, Charlie
