Part Number: TUSB4041I

Hi,

Customer would like to use TUSB4041 as below.

Is below connection possible?

For fast speed, if TUSB8020 is adopted at 1st tier, USB3.0 communication between PC and 1st tier and USB2.0 communication between devices and last tier. Is it correct?

Thanks.

    Hello,

    The block diagram is correct.

    If you connect a TUSB8020 to the PC, then the communication between the PC and TUSB8020 will be in both USB3.0 and USB2.0, since the hub in the far tiers are USB2.0 only, the communication between the PC and the USB devices will be USB2.0

    Regards
