Hi Team, we would like to confirm if the device can support. 8M camera and need 30f output.

Thank you.

Hi Mark,

What datatype will be transmitted through the CSI-2? As the bpp is needed to determine the video payload data rate.

Regards,

Logan

This will depend on the number of bits used in the video format.

Due to channel rate limitations, the 953 will not support any of the datatypes that use greater than 10bpp. RAW10 & RAW8 is possible.

For instance, RAW10 (with estimated 25% blanking/coding overhead) has a required rate of 3.1104Gbps while 953 has a maximum payload rate of 3.328 Gbps.

It should be checked/verified based on the specific pixel/line blanking and CSI-2 protocol overheads since its close to the maximum payload.

Logan
