Hi,

We have used 19.2MHz oscillator for CLKIN and REFCLK pins of CX3 used in our product and we have not used watchdog timer in our design.

During RE testing of the product with camera streaming at 220fps, the device fails at 720MHz, please refer below graph.

But when the camera is streaming at 30fps, the device does not fail, please refer below graph

Can someone please let me know the reason for this and its correlation with respect to frame rate

Thanks,

Menaka

Hello Menaka,

Can you please specify clock name that you are operating at 720MHz?

The maximum operating value of MIPI CSI Clock is 500 MHz.

Please describe the test and its expectation from the device.

Regards,

Sridhar
