Hello,
Apologies for making a mistake in the configuration. The CSI clock cannot be as large as 1120Mhz when we are using 4 lanes. Theoretically, the CSI clock cannot exceed 500MHz. Please let me know what exactly you meant by MIPI Data rate in your response 2?
Best Regards,

THS-Prepare and THS-Zero is not critical
H-Blanking: 2300
V-Blanking: 424
MIPI Data Rate: 1120MHz
Output Video Format RAW: CY_U3P_CSI_DF_RGB888

Hello,
Please find the snapshots of the Image Sensor configuration and CX3 Receiver Configuration Tabs of MIPI Configuration Utility Below:
Please note that the THS-Prepare and THS-Zero values are actually required to calculate the PHY time delay Value. In the above configuration, PHY Time delay value corresponds to that obtained by using the default values for THS-Prepare and THS-Zero presented by the MIPI Configuration Utility.

Hello,
Please let me know from where have you probed these traces. Are they probed from the sensor directly or from the test points available in CX3.
Also, please let me know if you are getting any MIPI errors. You can obtain this by enabling the macro CX3_DEBUG_ENABLED in cycx3_uvc.h.
Best Regards,

Hello,
Please probe the signals from the sensor and share it with me. This can be used to understand if the sensor is sending out data correctly or not.
Also, as I mentioned in my previous response, please enable the macro CX3_DEBUG_ENABLED in cycx3_uvc.h and share the UART debug logs.
Best Regards,
Jayakrishna
