What is the differential impedance should be at the clock signal between memory DDR3L and the processor Intel Atom E3805?

[RKhak]

In design guide indicated 68 ohm, in reference boards 85 ohm. What is correct?

Hi Rustres,

The processor http://ark.intel.com/products/84311/Intel-Atom-Processor-E3805-1M-Cache-1_33-GHz Intel® Atom™ Processor E3805 (1M Cache, 1.33 GHz) is an embedded CPU and due to that and the nature of your question I would recommend that you contact an Intel Field Application Engineer in your region.

Additional resources for embedded processors are available here:http://www.intel.com/content/www/us/en/embedded/embedded-design-center.html Resources for Embedded and IoT Designers

Thanks,
