J7EXPA01EVM: Question on the camera input and radar input design

Tool/software:

Hi,

You can find below sch in PROC082E4(001)_SCH.pdf (https://www.ti.com/lit/zip/sprr473).

In below sch, the Serdes input circuit design is different with camera and radar and also uses different connectors. Would you pls kindly explain why?

Thanks,

Chris
