What is the maximum bandwidth of fx3 iso mode on win10 ?

[siguc_3498911]

I am working on uvc iso mode on windows, my code work fine with 1080P 25FPS in YUV mode on win10。but when i rised fps to 30, it doesn't work.

Could it be bandwidth issue?

Hi,

CX3 can support up to 2.4 Gbps (300 MBps) throughput.

You should make sure that the throughput does not exceed 2.4 Gbps. The throughput can be determined by the formula given below:

Image throughput = bits per pixel × (Horizontal resolution + Horizontal blanking) × (Vertical resolution + vertical blanking) × frames per second

So, CX3 can support up to 60 fps in YUV 422 format.

Regards,

Eddie
