DS90UB960-Q1: DS90UB953-Q1 with DS90UB960-Q1 for interfacing 3 cameras with Jetson Nano

Part Number: DS90UB960-Q1

Hello everyone,

I was trying to explore Jetson Nano and interface 3 cameras with its MIPI interface. However i lately figured out that Jetson Nano development kit can only support one CSI-2 camera, even though the module supports 3x 4lane cameras.

So, I was thinking of using the TI's serializer and de-sirializer hub to get this to work. Need some valuable suggestions regarding its feasibility, before i proceed. I am attaching a screenshot of my idea. Please comment.

HI Sany

If the Jatson Nano board only has one CSI2 port, please check its CSI2 bandwidth, what is the lane rate (maximum) and how many lanes are supported inside Jetson Nano?

For 960 board, one CSI2 port can support ~6.4Gbps bandwidth with maximum lane rate 1.6Gbps@lane and 4 data lanes. If you need support 3 cameras from 953, please check the camera resolution. If it is 1920x1080@30fps with YUV422 camera video, the "3pcs 953 + 1pcs 960 with one CSI2 port" can work.

regards,

Seven

Hello Junqiang,

Thanks a lot for such a quick response.

For Jetson Nano, the camera spec says "12 lanes MIPI CSI-2 : 1.5 Gbps per lane". Also the camera that I intend to use is having a resolution of 1440 x 1080 and is providing 1.2 Gbps/lane max.

Does it sounds good in your opinion ? Anything else that i need to consider ? I would really appreciate your questions.

Thanks

Sany

Sany,

what is the frame rate? you can calculate the total bandwidth based on the 3camera system.

if the frame rate is 30fps, it has no any problem.

best regards,

Steven

Hello steven,

The camera spec says a max of 60fps for full resolution. however, our requirement is only anything >15FPS.

Sany,

The one CSI2 port solution between 3pcs 953 and UB960 with singe CSI2 output is workable for your application since it only has >15fps request.

best regards,

Steven
