AM5728: AM5728 ibis model

Part Number: AM5728

Hi,

After translation of the AM5728 ibis model, there are multiple models to choose from in the ibis file name in the SI model browser. How to choose the correct model?

  • Hi,

    The models differ for slew rate, voltage tolerance, and IO voltage level.

    If the IO voltage is 1.8V, then you should select one of the models 736-739. Use models 740-743 for IO voltage of 3.3V.

    You should check the datasheet for voltage tolerance. Models 738,739,742,743 correspond to 5%. The others are 10%.

    Lastly, models 736,738,740,742 correspond to fast slew rate. The others correspond to slow slew rate.

    Thanks,
    Kevin
