Hi all

 

 

I have a question about diffierenial clock termination design rules.

According to the DDR section of schematics tab in following Check List, it has following description.

 

 

DRAM_SDCKE0 and DRAM_SDCKE1 may be connected to individual 10 kohm 5% resistors to GND. Please click "Ref7" for more info.

 

 

 

 

I have a question about the description.

If user don't use DRAM_SDCKE1, user can leave the pin as "OPEN".

 

 

Is it correct ?

If no, please let me freescale's recommandation.
