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

Hi Miyamoto

there are no requirement for ripple noise for NVCC_XXX,

only requirement is that  these voltages should be within ranges

specified by datasheet.

Best regards

Hi,

I am using IMX6Q Sabre-Lite board. In that board there is a power short between 5v and ground section.The power indicating LED is blinking when connected to the supply.How can we fix this?

Kindly suggest the way to resolve the same.
