[Altera_Forum]

Is DDR3 support, using the Cyclone V soc hard controller, limited to certain speed grades?

Hi Ted, 

 I've looked at the Interface spec estimator. It doesn't specifically list the Cyclone V Soc parts. I'm interested in using an 5CSX part. The spec estimator refers to the Cyclone V GX but not the Cyclone V SX parts.

Yes it does. Depending on your browser window size, you may need to scroll down.

Ok. I got it. Thanks.

There are also speed grade checks built into the HPS component to make sure you don't request an interface speed that isn't supported for your particular speed grade.
