Dear Experts,
I understood from some of the materials that the trace length between the
driver to receiver ( signal path + return path) should be less than the rise
time. Is my understanding correct?
For example if the rise time of a signal is 1ns then the signal trace length
should be less than 3 inches( signal trace length 3 inches and return path 3
inches totally 6 inches = 1 ns of signal travel delay which is equal to rise
time of the signal)
If my understanding is wrong can anybody please provide me with some
materials to understand it. Sorry if this is bit basic question.
Thank you very much.
Mohamed Ali
