IBIS model for LMH6559

Other Parts Discussed in Thread: LMH6559

Hi,

We are using LMH6559 in our design and looking in to improving signal quality on the board.  I did find the PSPICE model, however I'd like to run some simulations on Linesim and hence would need IBIS model for LMH6559.

Thanks,
Sandeep.

    HI Sandeep,

    I'm checking into this. The part isn't spec'ed like a digital buffer, so I have concerns about the accuracy of an IBIS model. In general, a PSpice model should be more accurate. As long as the run times aren't too long, or you don't have convergence issues, a PSpice simulation would be preferable to an IBIS sim.

    Hi David,

    I am trying to find an appropriate stackup and termination for our board with LMH6559 on it and hence was using Hyperlynx Linesim to do this. I tried assigning the SPICE model provided on the product folder, but Linesim issues an error saying the header is incorrect. If you can at least provide the details of the driver used for input/output, it'd  help. 

    Thanks,
    Sandeep.
