Dear Jonathan
Thank you very much for your quick answer.
ADV3221 is analog device, so it needs SPICE model to simulate, I think too.
But in this case, I would like to check only the transmission quality, that means we would like to check an impedance matching.
So I think, it needs only a feature at the terminal.
I think it is better to simulate when it designs the board using fast signal.
I know, we doesn't have a simulation model, so my idea is to make a simple model.
Is that incorrect understanding?
Can I have a clear picture "to use the data supplied in the data sheet", you said?
Please show the better way to board design.
Thank you for your cooperation.
