Signal Integrity analysis is giving a very weird waveform for a tri
state buffer driver 164422.
There are two problems,
- a lot of ringing
- terrible distortion in waveshape
The track is 50 ohms and just 4 cms from driver to receiver.
The chip has a 25 series resistor in the output to help avoid SI
problems, but that does not seem to be working
Any ideas on why this could be happening and any things that can be tried
