Hi

Working with PCB´s, talking about crosstalk between source and receptor (victim), there are two parts of this: Forward  crosstalk and Backward  crosstalk.  For signals routed side by side, forward crosstalk requieres a distance related to "rise time" to becomes a problem.  For Backward crosstalk another distance.

Can anyone tell me about these distances (Forward and Backward)?  How I can make a calculation of those two critical crosstalk lengths?


Thanks in advance

Best regards,
