We would like to know behavior of cx3 when following configuration is set.

The sensor outputs a stream flux over mipi interface in a raw10 format. ie data lines have a packet header of 0x2B. We set the cx3 to raw10 input and the 16 bits output. But in this configuration, each 16 bits there are 10 bits of data and 6 zeros bits. This is not very interesting in terms of data rate.

Now, if we configure the mipi to a RGB888 input format and 24 bits ouput format, the data rate would be far superior. Problem is sensor outputs a raw10 format and so there are no 24h packet frame headers as expected by CX3 decoder : what is the behavior of cx3 decoder in this case ?

Thank you.

Lebrun,

The FE/FS and headers/footers are stripped off in the MIPI Bridge itself only the DATA will be remain in the buffers of MIPI CSI-2 bridge.

The control signals HSYNC and VSYNC and also clock will be generated by the MIPI CSI-2 bridge as per the inputs provided us. i.e MIPI CSI-2 configuration settings passed using CyU3PMipicsiSetIntfParams API.

Therefore, the GPIF II receives the data, clock and VSYNC and HSYNC.
