I want to know if there is an D/a module on Jetson TX2?

I want to use a GPIO to send some signals to control the speed of the servo motor on Jetson TX2,and also want to know the refresh rate of the GPIO on TX2

Hi, please check the GPIO clock and reset chapter for it, basically the output freq is less than 10Mhz.

Thanks,I want to know “the GPIO clock and reset chapter” in what document,you could give me the name of the document,I could download on the Jetson Download center.where I can found this content about “basically the output freq is less than 10Mhz”.
And I want to know if we can mount an D/A module on Jetson TX2,

It is in TRM https://developer.nvidia.com/embedded/downloads#.
TX2 only has digital output.
