Hi community.


Our customer has question below.


I have a question about the circuit board wiring pattern of DDR3-SDRAM to IMX6SLX.

In this our board, we have to consider the application of the Fly-by Topology wiring.

For wiring length spec of SDCLK, description of "IMX6SXHDG" of "Page33 Table 3-3" In Max.2.25 [inch], on the other hand: In the wiring example of "Page48 Table 3-6" is  2779.48 [mil] .

It  looks like does not meet the provisions.

Are you sure  do I think this is in any way?

Whitc is correct?



Although we started the board design in our company, it is currently difficult situation to meet the Max.2.25 [inch]. If possible, I want to relieve this spec.
