TUSB320: Does this IC work with USB3.0?

Part Number: TUSB320
Other Parts Discussed in Thread: TUSB322, TUSB321, TUSB542

Dear Team,

We are designing a portable gaming console and we want to use the USB 3.0 in a type C connector.

As per the USB controller, we have seen that your TUSB320 IC may fit on our product. Our requirements are listed below:

-          USB 3.0.

-          Type C connector.

-          Insertion and orientation detection.

-          Dual Role Port (DRP).

-          VBUS detection.

-          Mode detection.

-          Small size.

The only issue we have found with the IC is that, according to the datasheet, it seems that the TUSB320 is USB2.0 oriented, so we are wondering if is possible use it with USB3.0 in DRP mode.

I hope you can reply us and give us some other recommendation in the case the TUSB320 won’t fit our requirements.

In advance, thank you very much.

Regards,

Jesús

  • Hi Jesus,

    The TUSB320 is intended for USB2.0, hence this device does not fit the requirements for USB3.0, where you need VCON. On the other hand, we have the TUSB321 and TUSB322 that support USB3.0, even is the same die than TUSB320, but these devices can be controlled through GPIO/I2C. Please take a look into these devices. Please let me know any question.

  • Hi Luis,

    thank you for your response. I have been checking out the TUSB321 datasheet and it seems it is what we are looking for. As I mentioned in the first message, we are intending to use the IC as DRP role, but on the datasheet I only have seen a reference schematic for the DPF role. Could you provide me a reference schematic for the DRP? Does this IC have evaluation board?

    Regards,

    Jesús

  • Dear Luis,

    please, could you provide me feedback? In order to continue with the design stage of our product, we need a reference design for the TUSB321 working as DRP.

    In advance, thank you very much.

    My best regards,

    Jesús
  • Hello Jesus,

    Sorry for the delayed response. To set the device in DRP role, you just have to float PORT pin, hence you could take the Figure 4 as a design reference. As well, you could take a look into TUSB542 which is a USB Type C re-driver, so this device improve the signal integrity of the system. Figure 16 shows a Schematic example of DRP role. I hope this helps.
