Part Number: DS125DF410
The customer get DS125DF410 ibis-ami model with the request form from TI.com.The setting of de-emphasis in user's guide of ibis-ami model is following.
The setting of De-emphasis in DS125DF410 datasheet is following.
The register name are same, however De-emphasis setting is different, So the customer has a question.Which De-emphasis setting is used when the customer will run a simulation using ibis-ami model which TI provided? The de-emphasis is set like User's guide in simulation? or datasheet?Your advise would be so appreciated.Best Regards,Akihisa Tamazaki
The de-emphasis levels that apply to the simulation model are per the model user's guide.

Thank you so much for your comment. I have related question about IBIS-AMI model.
My customer is trying to use DS125DF410 and trying simulation using ibis- AIM model, however they found the deference between AMI user’s guide and latest datasheet.
As you reply at E2E, so I think that the ibis- AIM mode was built many years ago, then TI did not update AMI model for the latest DS125DF410. Is this correct?
If yes, the customer has some questions. 1. Are there any additional deference between AMI user’s guide and latest datasheet? 2. The result of simulation is too different from the real DS125DF410 performance when the customer use ibis- AIM model? If yes, what is the different?Would you please advise me?Best Regards,Akihisa Tamazaki

I do not expect significant difference between simulation result and measured DS125DF410 performance. Can the customer share their results?

Rodrigo-san,Thank you so much for your comment.The customer did not start simulation. They would like to know why there are some difference between AMI user’s guide and latest datasheet before evaluating.I would like to have last question.Does the customer set de-emphasis value which hows in AMI user’s guide? So the customer can get the result that they will use desired de-emphasis value. I believe that it is correct. However I would like to confirm again.Best Regards,Akihisa Tamazaki
