IBIS-Models for TFP410

Thanks Dan,

just what I needed!

Have a nice day,

Sean

Hi  Dan,

I am also looking for this model, but the link you put in this post is not valid.

The link go to the part number search or to the  forum but  not to the model.

Could you please attach the Ibis model.

Regards,

Patrick.

The link is not to the IBIS model - it is to the device folder.  The IBIS model is attached as file to the previous forum post.

Dan,

My apologies for the trouble, thank you for the fast answer.

Patrick

Hi Dan,

Does TFP410 has pre_emphasis for tmds outputs? I could not find that info in the datasheet. Ibis model gave me overshoot and ringings even though I terminate the differential lines with TFP401 input stage on the receiver side.

Thanks,

U Han, there isn't a dedicated pre-emphasis feature.  Does your simulation setup involve a DVI cable?  If so, what length?  A cable should attenuate overshoot.

Thanks,

Hi RossE,

Thanks for the reply. It does not include the DVI cable. It is on FR4 with 1.3 inch long differential traces. If I terminate the traces with 50 ohms pull up to vcc ringing got better. But if I use a DVI receiver ibis model (example: TFP401) on the receiver side, ringing got worse.

Thanks,

I believe the TFP410 was designed to drive up to a 5m DVI cable at max frequency, so it's no surprise that you're seeing lots of overshoot with just 1.3in of FR4.  You can also use the TFADJ resistor to reduce output swing.

Best regards,

Thanks for the input. For the TFADJ resistor, I will try it on the board but it is not possible during simulation stage. The differences on output waveforms between 50 ohm pull up resistors and TFP401 as a receiver  is huge.

Thanks,

UH
