Expansion I/O Speed on Jetson

I would like to use the Jetson for very broad (60 MHz bandwidth) and fast FFTs. I want to use the Expansion I/O for interfacing the board and I’m not sure if all the Expansion I/O pins are created equal, so if there are pins I should avoid using them.

I would need to send 16 bits in parallel plus a clock. Ideally this would be with the clock at 122.88MHz but half that would be fine also. If the clock could generate an interrupt that would be ideal.

My question: are the Expansion I/O pins capable of that?

Thanks in advance!
