Customer now found out that the undershoot voltage on Pin15/Pin16 is exceeding -0.3V lasting 8.4ns, and the maximum undershoot voltage can reach -0.46V_AC. Please help us judge whether this undershoot can meet our device requirements. Pls also find the detailed test waveform below. Many thanks.
I list the absolute maximum rating below for your reference. In my understanding, the -0.3V here is refer to DC voltage, right? So what's requirement for AV undershoot voltage?
