HD3SS3220: DRP reference schematics

Hi Ryan,

Customer cannot detect USB3.0, would you help confirm schematics? to send private message.

Hi Kevin,

I can look at the schematic on my side. Any adjusted schematics that can be sent through PM would be nice as well. In the meantime:

Have you adjusted the EQ settings on the TUSB501 at all? It could be that adjusting these settings will help the signal.

Can you send us the layout of the board being used via PM?

Does USB2.0 work?

Thanks,

Ryan

Hi Ryan,

TX signals of Pin6 and Pin7,
Should I connect to the Tx or Rx on the HOST side?

Hi Kevin.

I believe it should be TX to TX in this case. From what I can tell, it looks like the system is outputting signal to the TX pins of a USB-C connector.

If possible, could you help illustrate with a block diagram the system? I am having a hard time looking through the schematic to figure out where exactly the signal is coming from, and where it is going. If you could provide something like that, or explain the systems application, it would help me determine whether it should be TX to TX, or TX to RX.

Thanks,

Ryan

Host to Type C connector connection method. Is it correct?

Hi Jiunpeng,

It looks like the TUSB501's are flipped. Otherwise, I believe this looks correct.

Thanks,

Ryan
