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.

Hi ,
Since you are going to transmit DisplayPort, you could use 100 ohm.
Best Regards,
