About LMK04906 IBIS model

Other Parts Discussed in Thread: LMK04906

Hi,
We are using LMK04906 in our design.I have downloaded the IBIS model from your site. But its not correct.
1.Differential pins mentioned in the IBIS is not accordance with the datasheet
2.[Model] UWIRE_DIN
Model_type_Input
Vinh=0.4V
Vinl=1.6V
these should be interchanged
3.Data is non-monotonic: Will affect the clarity of the signal


Hope to get the answer and corrected IBIS model, as it is very critiacal for SI analysis. We are using Mentor Graphics HyperLynx tool.

Regards
Madhura

    Hi Madhura,

    What differential pins do not match the DS? Do you have the latest revisions of the IBIS models?
    I've contacted the IBIS modeling team to resolve these issues. Thanks for your patience.

    Hi Madhura,


    Our modeling team has confirmed this issue and plans to update this and the IV curves in the near future but should not largely impact modeling. We use Hyperlynx as our modeling tool as well.

    In the mean time, manually switch the Vinh and Vinl levels in the IBIS model until we release the fixed version to the web. At this time I do not have a confirmed update date set.
