Hi,

I'm searching for details to LPC5528, PLL0, spread spectrum.
I already read UM11126 chapter 4.5.69.1.5, but still don't know exactly how to use all the parameters correctly.

Is there an application note?

greetings

Bernhard

Hi,

Of course, the PLL0 module of LPC5528 supports spread spectrum feature, but I have found neither code nor application note for the feature.

This is an application note about the spread spectrum feature based on i.mxrt10xx, because the PLL IP is different, I suppose the AN is helpless.

Anyway, this is the an:
