Hello expert,
My customer is observing a strange waveform in positive polarity.
Below figure shows SOF packet, yellow is an receiving side (input to TUSB8041), red is transmitting side (output from TUSB8041).
Left figure is a setting in negative polarity, and right figure is positive polarity.
Left shows normal POE in negative polarity, but right is not normal POE in positive polarity (green circle)
Have you see this kind of problem?
Could you please give your comments or advice to solve the problem?
Best regards,
Katsu
