Device that can support up to 480Mbps data rate

Other Parts Discussed in Thread: TUSB2E22

Hi Experts,

Good day. I came to this forum with reference to my previous post:
SN74AXCH1T45: Data rate query

Based on our interaction there with an experts, the client responded as follows:

"But the problem is we don't have any IP to support USB 2.0 or eUSB.
So I am using an external PHY IC which can support USB2.0.The output of the TUSB2E22 repeater needs to be interfaced with that ULPI IC.
Hence the ULPI IC is compactable for USB2.0 the voltage level is 3.3V.
Also, I need to support both USB2.0 and eUSB in the system."

I am attaching their block diagram for your reference. Hence, they're looking for that kind of device that can support 1.2V to 3.3V and up to 480Mbps rate. Any thoughts on this?

Thank you for your support.

Regards,
Archie A.

    I do not understand this block diagram. The PHY would not output eUSB. Are the "eUSB" labels in the correct place?

    Archie,

    As Clemens said, the block diagram is a little unclear. Can you provide more information?

    Also, there aren't any transceivers in TRX that would support a data rate of 480Mpbs, this would fall into the HSD product line portfolio.

    Hi Experts,

    Thanks for your supports.

    The PHY output will be USB2.0 only. Hence he is looking for any PHY which supports both USB2.0 and eUSB (and we couldn't find it), he is proceeding with the USB2.0 PHY only.

    Do we have PHY which can support both USB2.0 and eUSB? 

    He just at least want to make the system voltage compactable for both USB2.0 and eUSB. Thus, wanted to add a voltage level translator in between TUSB2E22 and MUX on the eUSB net.

    Thank you.

    Regards,

    eUSB is never used with USB type C connectors. I do not understand what problem would be solved with this.

    If you want to access both USB and eUSB devices, you need separate ports. To do this with one ULPI PHY, you need to insert a hub, and add the TUSB2E22 to any downstream ports for eUSB.
