Hi Ti Team,
Does HD3SS460 support switching to USB3.0 when TypeC is used as a downlink port?If so, how should it be set?

Hi Smith,
Correct HD3SS460 could be used here. This device is a passive mux for USB and alternate mode applications. Will your Type-C port support any USB-C alternate modes? If not TMUXHS4412 could be used.
Also passive muxes should be used when signal integrity (SI) is not a concern (i.e. short PCB trace, <~4.5 in). If SI is a concern the active muxes like TUSB1042I and TUSB1146 (alternate mode applications) should be used.
