HD3SS3202: How PC know if the MUX support 10Gbps or 5Gbps

Part Number: HD3SS3202

Hi Team,

I have a question about how PC recognize the speed of the MUX. Could you please help? Thanks!

For example, if the PC supports 10Gbps, when a type-c port with HD3SS3202 is connected to PC, how does the PC know if the type-c supports 10Gbps or 5Gbps?

What if the cable connected between PC and Type-C port can only support 5Gbps, will the PC send the data at the speed of 10Gbps or 5Gbps?

Best Regards,

Hao
