Tool/software:
Hello, I'm planning on using the TUSB8041IR for in-car system and I have some questions:
1. is it possible for someone to review my schematic and provide some inputs
2. Do I need to use some ESD protection on those ports or the TVS diodes shown below will be enough.
Hi:
1: for USB3 signal, you can not connect SSTX1 and SSTX2 together due to signal integrity issue. you need HD3SS3220 for type-C port.
2: what purple color mean? installed or not installed.
3: ESD part looks good to me.

Thank you for your prompt reply, I appreciate it.
1. I have changed USB-C to Type-A (3.0).
2. The pink marking indicates 'Do not populate'.
3. I also added a common mode choke—let me know if you think it's unnecessary, and I can remove it.
4. For the Port 3 on the HUB I'm only using DP & DM (for a USB2.0 device ) is it ok to leave SSTX& SSRX floating unconnected?
HI ;
Please connect SSTX_UP to SSTX of USB conenctor and SSRX_UP to SSRX of connector.

To clarify, I am referring to Port 3 of the USB hub, as shown in the diagram/image below. is it ok to leave SSTX& SSRX floating unconnected?
