Other Parts Discussed in Thread: TFP410

Hi,

I' d like to ask about TFP410 IBIS model.

I could get IBIS model from thread below.

http://e2e.ti.com/support/interface/high_speed_interface/f/138/p/56563/207573.aspx#207573

But I can't find the parameter to adjust TFADJ in this model.

How to control the amplitude of the DVI output voltage swing?

Hello Yaita-san,

The model name for this terminal is "esd_nfs_dvcc" and it is located on the attached ibis model.

Is this what you are trying to find?

Regards.

Hi Elias-san,

Yes, I found the model "esd_nfs_dvcc".

If I use this model, is it possible to control by setting pullup resistor(505~515Ω) connected to TVdd on TFADJ?

I'm sorry for basic question.(I'm unskilled about description of IBIS model.)

Best Regards,

Hello Yaita-san,

I think you will have to control this feature externally. I have asked to the simulation experts for more information and I'll reply back when I get answer from them.

Elias-san,

Is there any update?

If it isn't, could you push your simulation team again?

I'm afraid to urge you, but I will have to answer my customer's question.

Hello Yaita-san,

I apologize for the delay.

It seems like this value can not be adjusted on simulation.

What are the issues you are having?

I have attached some reference values taken from our evaluation module.

Regards.

Elias-san,

I talked my customer and he asked me additional question.

He concerns the amplitude of the DVI output voltage swing in this IBIS model.

Is DVI output swing voltage 500mVp-p in this IBIS model?

(TFP410 datasheet P.7)

My customer wants to know this model to simulate.

Hello Yaita-san,

I've sent a request to the ibis guys to tell us what the voltage swing is in the model.

Why is this a concern for the customer?

Elias-san,

Thank you for your continuous support.

My customer currently prepares IBIS simulation environment.

It is a simple question for my customer.(Problem isn't occured yet.)
