So my question is what should be done with the VSSDSI pin when DSI is not used?

Hi Sara,Thanks for getting back to me. I am not allow to share to much but this is what is called and Active Electrical Cable (AEC) for QSFP. I see you pointed out that the VDDDSI pin but my email shows VSSSDI which should be VSSDSI. My mistake.

On a STM32L4R9 one of our designs wants the VSSSDI pin to be connected to ground through a capacitor (not directly connected to ground) when the DSI is not used. But in the datasheet it states that if DSI is not used it should be grounded?
