Does the ddr3 descrete components' command & address signals need termination resistors for c10?

[WLin30]

I have design a board c5+descrete ddr3 component which command & address signals do not have termination resistors which run ok. I am not sure wheter C10  also ok for such design.

Hi,

The DDR3 discrete components' command & address signals are required the termination resistor.

In Cyclone 10, you can use the internal termination scheme such as on-chip termination (OCT) and on-die termination (ODT) instead of external termination resistor.

You can always refer to Cyclone 10 EMIF User Guide in the link below.

May I know whether you setup the OCT and ODT on your design Cyclone V with DDR3?

Thanks.

Do you mean that by setting Cyclone10's OCT/ODT that need not external termination resistor?

If yes, how to set the EMIF's parameters?

Hi Sir,

You can set your EMIF's parameter according to your memory spec and datasheet.

For the OCT/ODT, you are encourage to perform on board simulation to get the optimal value.

As I stated in my previous comment, you can always refer to the Cyclone 10 EMIF User Guide to setup your EMIF's parameter.

Thanks.

Hi Sir,

Do you have any question regarding to this topic?

Thanks,

Hi WLin30,

I hope you are doing well.

I have to close the case since you don't have further question for this case.

You can always file a new case if you get the problem or issue in using the Intel product.

Thank you for using Intel Community.

Regards,
