DS90UB953-Q1: Transmission distance of CSI-2 signals

Torsten Dr. Kilias

Part Number: DS90UB953-Q1

Hello team,

in the context of applying LVDS ICs like DS90UB95* following question occur:

Are there any definitions of trace length of CSI-2 signals at PCBs or if there is a wired connection like a FFC cable?

I am sure it depends on lane speed, but I did not find any remarks to that (even not at "MIPI Alliance Specification for
Camera Serial Interface 2 (CSI-2)").

Thanks for your immediately answer.

Could you be so kind to go more in detail concerning the mentioned standard?

Hello Torsten,

This is not our standards and we do not define the limits. So please get all the details from MIPI.

I just can tell you what I see people implement in their designs. Normally they limit the max length to 10cm.
