Hi team,

My customer is looking for 3:1 MUX for USB3.1 Gen2, but it seems we have 2:1 MUX only. Could you please comment the proposal below or provide any better solutions? Thanks!

Best regards,

one 3212 is just marginal for USB3.1 gen2, two muxes have too much loss for gen2.

you may try our new device TNUXHS4212, It has higher BW than 3212.

Hi Sam,

You have the right idea however the USB-C will need its own 2:1 switch. Type-C connectors have two pairs high speed pairs for 10 Gbps traffic. I recommend replacing the second TUSB1002A with TUSB1042I. The Micro USB connector may need a TUSB1002A depending on the PCB layout and trace length. What is the application here?
