GPIO max read frequency

[Eximius]

Hi,

We are working with a 13 bit or 9 bit parallel camera interface with clocks at 48Mhz or 24Mhz. And I would like to know what is the GPIOs max reading frequency, or if there is another interface that the camera could be directly connected to, without the needs of extra hardware.

Platform: i.MX 8M Plus

Thanks for your help.

Best regards,

Hi Eximius,

The max speed on GPIO can be found on the datasheet 3.5.1 General purpose I/O AC parameters:

And the processor has interfaces focus on a single Camera, MIPI CSI 1 can support up to 400/500 MHz pixel clock in the
Nominal/Overdrive mode.
