Hi
In The Datasheet of AM335X , for the DDR3 Data signals routing it is mentioned that the Nominal etch length of the DQ lines is DQLM , which is the longest Manhattan length .
What if the Etch length is more than the Max Manhattan and we do the length matching to the longest trace. Will it be an issue.
Ie suppose my DQ5 is having the max Manhattan of about 790mils , and my DQ1 is having Manhattan of about 690 and etch length of 990 mils, what should i do ? Length match DQ1 and all others to DQ5 or Length match DQ5 and others to Dq1.
Right Now the Max Manhattan Distance is for 790 mils ( DQ5 ) and all the traces are length matched to 970Mils +/- 10 mils.
Please advice on the same .
Should i Length match to 790Mils +/- 10 mils or the present one is ok.
regards
Eby Jayan
