I recommend putting 100R resistors in the input lines.
If you see different patterns at high speeds, it can be caused by the impedance mismatch of cable to input.
The reflections can distort the signal. The resistor will dump the reflection.
The resistor will also limit the current if a signal is above the power rails.

Nice project, thumbs up
