LMH1981 VSout and HSout

Are the VSout and HSout pins are driven differently than the OEout or VFout, etc.  Scope shots show quite a difference in these nets.  That and the Ibis model is a different output driver for the HSout pin.

    Hi Jaden,

    Thanks for the feedback.

    HSOUT (OBUF_HS) uses a different output buffer from the rest of the outputs (OBUF).

    I checked with our IBIS modeling engineer on this LMH1981 IBIS model, and he found an error with the HSOUT output buffer (OBUF_HS).  It has been fixed and the new model should released to the web by tomorrow or the next day.

    Best regards,
    Alan
