DS16F95QML-SP?

    Hi Kannan,

    We do not have a SPICE model for this transceiver. We do not provide SPICE models in general for our transceivers.

    Best,

    Thanks Ethan. 

    I had Kannan ask this for me because I was having trouble figuring out how to post the question myself. I was hoping that there might be a SPICE model because the product page shows PSPICE-FOR-TI and TINA-TI under "Design Tools and Simulation." I will have to keep working with the generic model of an RS-485 driver that one of my coworkers built. 

    You can mark this as "resolved."

    Hi Colton,

    Today is a public holiday. Please help give some time for some feedback, thanks.

    Best Regards,

    Hi Colton,

    No worries, this is a very reasonable request. We don't give out PSPICE models because it reveals some of our protected IP. We used to years ago, but have since moved away from it (which is also why the sim tool links are still present). 

    The one thing that might be helpful that we can provide is an IBIS model. These can be converted to SPICE models using other sim tools (not ours due to legal/software licensing issues unfortunately). 

    We have an IBIS model for the military grade version of this device (DS16F95), which could get you closer to an actual model:

    Thanks Ethan, 

    I will look at this IBIS model and see what I can do with it. That's a step-up from trying to develop my model using the datasheet. Slight smile

    If the concern is protecting your IP, PSPICE does have the ability to encrypt models. I know that Renesas uses encrypted models for that very reason. Just a thought, but I'm not a business person and I'm sure that the TI engineers already knew about that.

    Hi Colton,

    I appreciate the suggestion. I know our design team is aware of the encryption, but I believe there was some other reason as well. 

    In the future, feel free to reach out to us directly on E2E for any other device related questions. The engineers responsible for each particular device will be assigned to your question. We aim to get you a response within 24hrs. Just click the "Ask a new question" button and select "Technical & design support" and "Hardware development & troubleshooting."

    Best of luck,

    -Ethan
