This is a SPI Clock. 6.25MHz frequency. I see something like a reflection. I don't think it's from cross talk on my board from another signal, not sure.
Added as requested: This is my system diagram (notice I have a stub). Note that the diagram ends at the "Connector". There is a cable to the SPI Slave beyond the "Connector" but that is not even connected when doing the measurement.
What kind of terminations should I try to get rid of this reflection? Should I try to play around with the termination values or try to remove the stub?
