Hi team,

I will use the camera module integrate 953, its CSI_CLK is 184MHz and it use 4-lane of CSI-2.

I will use 954 to set 400MHz CSI_CLK and 2-lane.

Will CSI output of 954 is in intermittent operation?

Best regards,

Hello,
If the 953 input is slower compared to the 954 output, the 954 will only output the CSI data when data packet is available to send out. It will go into the low power state according to MIPI CSI-2 specification when no data is available to send out.
