    Worst-case voltage Drop - HX2LV

    ShMi_1495391

      Hello

       

      I have a question about CY7C65632-48AXC.
      There is description below in the "Operating Conditions (page 19)" of HX2LV datasheet.
      https://www.cypress.com/file/114101/download
      「5 V supply voltage to ground potential ......4.75 V to +5.25 V」

       

      While, there is description below in the "7.2.2 Voltage Drop Budget(page 175)" of the USB 2.0 specification.
      「The voltage supplied by low-powered hub ports is 4.4 V to 5.25 V.」

       

      If the voltage drop is the worst, can HX2LV not keep with this USB 2.0 specification?

       

      Best Regards
