Hi David,

Thanks for your suggestion.

How about TS3USB31RSER ? It is simple for our design.

But it seems the pin location is not ideal for USB differential signals. (See attached)

TS3USB31RSER would fit your application.

For this design, you would route the signal as single ended trace with 45ohm impedance.

Thanks
