MIPI CSI-2 capabilities vs data lanes

[g_moreno]

Hello,

About the MIPI CSI-2 capabilities, I would like to confirm if the following calculation is correct: for 1920 x 1080 @ 30 fps in video mode, do I need at least 3 data lanes?

F = 1920 * 1080 * 30 * 1.35 * 2 (cycles per pixel) = 168MHz

According to i.MX6QRM Rev. 2 page 2733, maximum bandwith for 2 lanes is 125MHz.

Thank you!

Hi Guillermo

I believe your calculations are correct, 3 data lanes are needed.

Best regards
