Good morning everybody,
I'm using a SN65LBC179Q in a digital differential transmission. With 5m cable everything is spick and span, however, when using a 50m cable, the signal looks odd at the sender side:
The graph shows the positive line vs. GND (red), the negative line vs. GND (blue) and positive vs. negative (green). I understand overshoot and ringing, but I do not understand the short delay / pause (~500ns) during both swithing edges: Are these due to the ic's current limit? How is the current limit implemented? Does it create a siwth-off for a defined time or does it limit the current anlalogue?
