TUSB2E221: Enquire data lines status when /reset pin is asserted.

Part Number: TUSB2E221

Hi,

If /RESET pin is low, TUSB2E221 will run into power down mode.

May I know whether the DPx, DNx, eDPx and eDNx are Hi-Z in reset state?

That means the mux will disconnect between eUSB and USB2.

 

Thanks, and best regards,

Tiger

    Hi Tiger,

    When the repeater is put into reset, the data lanes are Hi-Z:

    That would disconnect any USB2 connection.

    Just curious, is your customer looking into this because they want to maintain USB2 functionality even when the repeater is in reset? Or for a different reason?

    Thanks,

    Ryan
