Hello,

Please find the attached CX3 MIPI receiver settings. Please note that the settings populated under the "CX3 MIPI Interface Configuration" section of the tool can be tuned as per the user's requirements (provided that the values are in min/max range)

You can refer to this KBA Steps to Setup up MIPI CSI Camera Solution with CX3 – KBA225748  to generate the firmware using the tool.

The total bandwidth that can be practically supported by USB 2.0 (high speed/full speed) ~ 25 - 30 MBps

So 2592*1944*1*3 =  30 MBps

Please let me know if any queries on this.

Regards,

Rashi
