SN65HVS882: SN65HVS882

Part Number: SN65HVS882

Hi,

I'm designing a digital input card for which I've selected SN65HVS882 Digital Input Serializer that suits my purpose. Kindly let me know how do I go with the PSpice simulation using this model as I'm not able to find SPICE model for this.

Thanks

  • Hi Sinchana,

    We do not have a PSPICE model available for this device and due to it being an older device it is most likely not going to get a PSPICE file. Due the complexity of the part there is no simple model that can be used as a stand in for this device. At this time the only model available is the IBIS model.

    If you have any other questions please let me know.

    Best,

  • Hi Parker,

    Yeah I've found that there is an IBIS model but it is not sufficient to perform the simulation purpose, please let me know what is the alternative solution to overcome this issue and design my Digital Input Card.

    Thanks

  • Hi Sinchana,

    All the necessary design information is within the datasheet. Is there any part of the datasheet that you have questions on or any part of the design that you need any guidance on? 

    Besides estimations that you can gather from the datasheet we do have an EVM for this device: https://www.ti.com/tool/SN65HVS882EVM and that is the best bet for testing the part to understand how it works. Since we don't have simulation models this is the best thing we have to offer. 

    That being said though, if you have any specific questions about implementation, design, or limitations of the device please let me know and I will see what I can do  to help you design with this part.

    Best,

  • Hi Parker,

    Thanks for sharing all the possible ways. I did have a look at the datasheet and EVM kit for the awareness.

    But my concern is to design a customized Digital Input PCB card with good number of inputs, for which I need to understand the performance of SN65HVS882 through simulation first. So the need is to find a suitable path to implement it to understand the behavior and I have thought of simulating it in PSpice but not finding a SPICE model of it instead only IBIS model but even that is not sufficient for simulation, kindly help me to find a way.

    Thanks,

  • Hi Sinchana,

    The issue is we don't have a model and our resources that are tied to developing other models that are higher priority at the moment. This part is not currently slated to have a model so there isn't much we can do on the simulation front.

    We do have an equivalent model of the inputs as shown below

    Which will give an idea of high the inputs are being monitored - but beyond the information in the datasheet along with testing abilities of the EVM this is what we have available and it is all that is planned for this device so there most likely will not be a model developed for this part.

    If you have any particular question on operation of this device please let me know

    Best,
