    Currently I am referring to IBIS model within sprm705.zip (https://www.ti.com/lit/zip/sprm705)

    The Data Models have not  defined Receiver Threshold section  (AC and DC thresholds) as well as Vmeas.

    Pl refer the section with details on each specific model. For e.g. for the below model I have highlighted the portion where this information is located.

    regards,
