Dear all,


We have a question about Spread Spectrum of PLL2 of i.MX6UL.


Only PLL2(SystemPLL) supports Spread Spectrum.

We want to use this Spread Spectrum for a peripheral.


However, this PLL2 is used for MMDC module.

When DDR3L is used, may this Spread Spectrum cause any trouble?


In this case should PLL4 be chosen for MMDC?


May I have advice?


Best Regards,
