Camera MIPI length

Hi support,

Following NX design guideline, maximum trace delay at 1.5Gbps is 800 ps, that is about 12 cm PCB trace lenth.

Actually this is very small number. However I saw some vendor they design cable with 30 cm and camera can work with Nano, AGX. So my concern is that is this right number? What does happen if I design PCB trace length over 12 cm for MIPI?

Thanks

The maximum trace delay limit is almost same on NX, Nano or AGX. Custom design should follow that. You can check with vendor why not follow that. We strongly recommend to follow the rule.
