Hi,

 

Why IMX6UL Reference schematic design used 470 ohm for DDR Differential clock termination instead of 100 ohm?

 

Is there any reason releated to Silicon version issue?

 

I have checked about this in Hardware design document, datasheet, Reference manual. But i didn't get those details?

Please help me on this.

 

 

 

Thanks in advance,

 

Regards,

Ramesh
