Maximum number of CSI-2 and GMSL cameras that can be integrated with Xavier

Greetings, everyone!

Nvidia Xavier developer kit has (16x) CSI-2 Lanes. TX2 has 12x CSI-2 lanes, and it can support 6 cameras quoted from https://www.nvidia.com/en-us/autonomous-machines/embedded-systems-dev-kits-modules/. I need to know how many can the Xavier support, my guess is 8. Also, how many GSML cameras will the Xavier support because I need to mount cameras at distance ~ 15 meters from the Xavier.

Hi ebraheem,

“I need to mount cameras at distance ~ 15 meters from the Xavier.” --> How many GSML cameras required on your project? Please contact with NVIDIA camera partners for the support.

Thanks

I want to mount at minimum 8 cameras.

Hi ebraheem,

To connect 8 GMSL camera on Xavier is no problem, but not sure the resolution and details, still, please contact with our camera for the support, you can find their information from: https://developer.nvidia.com/embedded/community/ecosystem#hardware_design

Thanks

Hi ebraheem,

To give you a little more detail on this:

There are 4x 4-lane MIPI/CSI-2 interfaces on the Jetson AGX Xavier. Two of these interfaces can be broken up into 2-lane MIPI/CSI-2. So, without virtual channel support in software Xavier can support 6 cameras.

4x 2-lane MIPI/CSI-2
2x 4-lane MIPI/CSI-2

Software support for virtual channels will be coming for Xavier very soon. D3 Engineering is a Jetson camera scaling partner and will be supporting this once it is available. With virtual channels, up to 16 cameras will be achievable.

D3 also offers FPD-Link III and GMSL2 Ser/Des cameras to meet your distance requirement. Feel free to contact us for more information!

Jason

Hey Jenson,
Thanks for the reply. One question, CSI-2 cameras don’t meet my distance requirement. So, how many max GMSL2 cameras can the Xavier support?

Hi ebraheem,

The answer is still 6 without virtual channels, and 16 with virtual channels.

Jason
