The schematic looks correct.

What is their data rate ad what is the distance before and after the two DPHY440SS?

Thanks

Hi David

1) My mainboard provides 4-lane DSI, each of them can operate up to a maximum bit rate of 1.5Gbps.

2) I typed the length of CSI and DSI in the photo.

Thank you

12in is around 3dB loss at 750MHz, so we should be ok.

Thanks
