SDRAM PCB layout

Unread post by fooji »

Hi angry Sorgelig,

I'm working on my own add-on for MiSTer including SDRAM. Will be published under GPL 3 when finished. I saw the layout of the XSD module with two SDRAM chips. How sensitive is this layout regarding impedance and length of traces and crosstalk? Originally planned on a two layer board, but don't think it will work out.

Same applies for USB, same question here. Is it really that sensitive?

try, Fooji
