Talking about signal quality. Could somebody tell me about the criteria
of overshoot, undershoot, overshoot ring back, and
undershoot ring back for TTL(5V) , CMOS(5V), LVTTL(3.3V) logic types?
Intel has provided the GTL+ (Vtt=1.5V, Vref=1.0) criterion for signal
over/under shoot =0.2*(Vtt) ,
Thanks you in advance,
