    How to control characteristic impedance in CCG3 displayport dongle design


      Now I design a type c to displayport  with CCG3 devices,and I use a 4:6 switch(parade:ps8742B) .

      I'm not sure how to control the characteristic impedance of the SSRX1±、SSRX2±、SSTX1±、SSTX2± ,because these signals may carry usb_ss signal or

      displayport signal, usb_ss signal characteristic impedance is usually controlled to 90ohm,whereas displayport is usually controlled to 100ohm.
