    Hi,

    Are we referring to the High Speed Input/Output, or the 2-level/4-level control pins? 

    4-level controls pins are 3.3V.

    2-level control pins are 1.8V or 3.3V depends on the VIO_SEL setting

    High Speed RX differential peak-to-peak voltage swing dynamic range is 2Vpp

    High Speed TX dynamic differential voltage swing range is 1.5Vpp

    For more detail, please refer to Section 5.5 Electrical Characteristics in the TUSB1044 datasheet.

    Thanks
