Can IMX8ulp's 4 lanes MIPI-DSI support 720P (720 X 3 RGB X 1280) at 60 frames per second? if not, what frame speed can be supported? 30, 20 ,15 or less? Thanks.

Hello @zlxie,

I hope you are doing well.

Please refer to Chapter 61 MIPI-DSI Host Controller (MIPI-DSI) from the link below.

It will help you

Thanks & Regards,

Hi,

That doesn't answer the question though. The chapter only mentions:

"This module does not support the 74.25 MHz pixel clock rate generation for 720p60 and 1080p30 resolutions."

But it doesn't say the maximum pixel clock supported and therefore what framerate can be achieved at 720p (45fps)?

Regards,

Gary
