Part Number: HD3SS3220
I'm using HD3SS3220 and TS5USBC412 in a project.
I want to use one USB-C port as third functions.
Console & OTG & Host (opposite direction). These are different ports.
An idea is that;
Role of USB-C will be set by the type of connected device.
HD3SS3220 is in DRP mode and provides a proper USB2.0 direction path by CC pins on usb-c connector. Right?
When a laptop or PC connected to usb-c, HD3SS can sense it and will be set as UFP own.
When a peripheral (like a usb flash disk), will be set as DFP own.
There is a bidirectional USB2.0 mux (TS3USB221) at the output of port controller.
USB power provider will be supported by ideal diode ICs against power conflict.
Seems work in principle. Agree?
USB2 should work, also you don't need TS5USBC412, DP1/DP2 are connected at Type C conector
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Brian Zhou:
Thanks for your reply.
I thinked to do it against signal reflection effect on unloaded 2.0 line.
Will I face reclection effect when top&bottom 2.0 lines when used in parallel?
Because I couldn't sure that regular type-c cable (in markets) has seperate usb2.0 lines or single 2.0 line.
In reply to ali kelem:
how many usb2 lines goes into type-c,
One usb2 line will be using. I think usb-c cable (plug) has just single usb2 pair.
If so, I don't need usb2 mux IC, as you said.
Finally, I see (lately) that a standard usb-c_to_usb2 cable has single usb2 line.
Sorry for taking your time by second question.
