Hi,Avtaar
it depends on how long your trace.
For serdes, the FR4 always is not a problem. In the stage of chip design, it
has considered the effect of Loss using circuit method to overcome it.
i think you should get a idea about what your chip is used for, the using AMI
model get a rough estimation.
Thanks.
Tesla.
