Nvcsi Rx and Csi-2 Tx compatibility check

Hi All,

NVCSI spec:

  • Supports both D-PHY, v1.2 and C-PHY, v1.0
  • MIPI CSI-2, v1.3, protocol stack

Our CSI-2 Tx Spec:

  • D-PHY Specification, version 1.1
  • MIPI CSI-2 standard, v1.1

Whether both are compatible or not? Any extra configuration is required between these devices?

-Thanks.

Suppose it’s backward compatible.

Need to confirm the compatible.

What are the points, we need to check for this.

-Thanks.

In link, Image Sensors World: MIPI Alliance Officially Releases C-PHY v1.0, D-PHY v1.2, and M-PHY v3.1 Specs

It is given as:

The updated MIPI D-PHY specification, v1.2, introduces lane-based data skew control in the receiver to achieve a peak transmission rate of 2.5 Gbps/lane or 10 Gbps over 4 lanes, compared to the v1.1 peak transmission rate of 1.5 Gbps/lane or 6 Gbps over 4 lanes.

It is mentioned that data rate is varying between two versions. So need to confirm the compatible between
two ends.

Please ask Nvcsi team regarding this.

-Thanks.

I believe that tell the max support for V1.2 is 2.5G and also support the speed below 2.5G
