Atom E3950 MMC AC timing

Hi there,

I am a hardware developer.

Our customer wanted us to show ATOM E3950 emmc AC timing interface in HS400 mode that the setup and hold time got margin in design.

We checked from spec Doc #557555 and JEDEC emmc spec v5.1.

We figured out the tDVW = 2.399nsec min., tISU requires 0.4nsec min.

Can Intel FAE give me some support on how to prove that the interface timing can fulfill the JEDEC requirement?

Our customer wanted to confirm the design is without timing error.

Please help to review and give us comment on our understanding.

Best Regards

Jackie Wong
