Dear Team,

I am writing this on behalf of hardware team,

What is the maximum allowable track length for SD (to be used with UHS-I cards)

Thanks,

Hi,

You should follow the processors.wiki.ti.com/.../AM57xx_Schematic_Checklist There are no specific recommendations from TI for trace length. If in doubt you should do SI analysis.

Hi Biser,

Thanks for your response. From the link you shared we could not muster information regarding trace length.

As a standard practice we see SD maximum trace length is less than 100mm, can you please confirm if this is applicable to AM571x CPU series.

Thanks,

Vamshi G.
