Hi community.

Our customer want to use SSC function of PLL1 and PLL2 .Becouse There are noise issues.

I read  Vybrid RM of sect 9.4.2 Spred Spectrum but i could not be well understood. .

Do I get the recommended value to be set to specifically PLL1 and PLL2.

Frequency, width, step does not matter in the recommended settings.

Hi,

There is a document for iMX6 devices. enable the spread spectrum

The clocking of both devices are similar and I think it can help.

Are you trying to achieve an specific modulation frequency and depth?

Best Regards,

Alejandro
