Hi
Thank you all. I understand the theory behind TDR. But I am confused about
calculating the rise time to be used for simulation.
In the formula 0.35/BW. what is the bandwidth here? is it the data Nyquist
frequency?
Lets say the data rate is 28Gbps, how to calculate rise time based on
10%-90% calculation and how does it change for 20%-80%?
Regards
Dan

Subject: [SI-LIST] TDR Rise time
Hi,
Can I get help in understanding TDR rise time calculation? I came across
10% to 90% calculation and 20% to 80% as well. Just wanted to know what is
the difference between them and how to calculate the TDR rise time.
Thanks for the help.
Regards
Dan
