Hi All,

 

We are designing an power pc system with for sdrams. We are wondering if there is any need to trace lenght matching, number of vias and empedance calculations for such a system memories will work at 133Mhz?

We have also seen reference designs which has series resistors to address and data buses. Is there any real need for series resistors on address and data buses?

 

Thenks for your ideas.

Mehmet
