SN55LVDS33-SP: IBIS simulation in ADS is not showing proper result.

Kumar Harshit1

Part Number: SN55LVDS33-SP

I am trying to do an signal integrity simulation using SN55LVD31W-SP and SN55LVD33W-SP IBIS model in ADS software. After loading the IBIS models, they are not showing differential pins and the simulation is not running properly. I have attached the screenshots.

You have to select the pins you want to model after loading the IBIS:

In the IBIS model I have loaded, any option to enable other pins is not coming. Can you let me know how to enable those pins.

Hi Anyiam,

Thank you for your support. I was able to replicate your schematic and it is working properly. I still have an issue, can I get a digital output out of the LVDS receiver in place of the digital one. Is it supported by the model?

Hi Kumar,

I haven't been able to do that myself - I think it may be a limitation of ADS.

Hi Anyiam,

Will I be able to get the analog output, if i do the simulation in some other software like Hyperlynx or Zuken? I want to feed that signal to next components.

Hi Kumar,

Probably, but I'm not completely sure. We only have ADS here to use.
