How can I eliminate the overshoot and/or undershoot on the clock line and the control lines to my Analog to Digital Converter?
The overshoot and/or undershoot is caused by fast signal edges combined with a poorly matched signal termination. Add a 47 to 100 Ω resistor in series with the input, located as close to the clock source as you possibly can. The purpose is to match the source impedance to that of the clock line, which should be considered a transmission line. The series termination uses little additional power and is usually sufficient to minimize the ringing effect.
