i.MX6ULL SDIO SDR50/SDR104 design question

According to the 3.5.2 high speed signal routing recommandations in i.MX6ULL hardware development guide Revision 0 <https://www.nxp.com/webapp/Download?colCode=IMX6ULLHDG>, CLK should be longer than the longest signal in the Data/CMD group (+5 mils). Can customer place the Micro SD connector at 7 inches away from the i.MX6ULL for running on SDR50/SDR104 speed?

Hi Mike

 

yes this is possible. May be recommended to perform ibis modelling to obtain

optimal board layout.

 

Best regards
