We started some product with the K70.
To develop it, we used the tower K70 which include an external RAM end DDR.
Then, we bought a commercial product, a small board which include K70, a DDR and a Nandflash.
Now, we want product Our self our board with these element.
But we know we must take care of a track between the K70 and RAM / DDR.
What are the particular action do design properly a PCB with these 3 element (Track length?, Impedence...??)
Are they some application note about this?
