Hi team,

 

I would like to ask about the ripple noise for i.MX6DQ power rails.

I found the description as below in i.MX6DQ hardware development guide.

“Common requirement for ripple noise should be less than 5% Vp-p of supply voltage average value.

Related power rails affected: all VDD_xxx_IN and VDD_xxx_CAP.”

 

How about the other NVCC_XXX power rails than VDD_xxx_IN and VDD_xxx_CAP?

 

Thanks,

Miyamoto
