Hi all:
I am currently working on a high speed differential trace
characterization up to 28Gbps, the problem is the high insertion loss, your
signals has degraded just for several inches. So this company comes up with
this tools to calculate the emphasis taps you can add into your PG to
compensate the loss and reopen the eye. I was so confused by the way how they
calculate it, because sometime they won't give you the best optimized taps.
Any suggestion to full understand the Pre-emphasis Vs. insertion loss?
Thanks
