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.

Hi Ko-hey
right, it can be left as "OPEN",
for example as in Sabre schematic spf-27392 p.4
signal DRAM_SDCKE1
Best regards
igor
