TDP2004-Q1: TDP2004 for DP2.1 application

Part Number: TDP2004-Q1

Hello, 

We're designing DP2.1 TX interface using TDP2004-Q1. 

The topology of impedance of this design as below, what is the suggested PCB trace impedance for DP2.1 application? 

FPGA Pkg impedance(93ohms)-> PCB trace 93ohms->Redriver(?ohms)->Connector+DP80 cable

ADo you have specific layout rules for DP2.1 (UHBR20) 4 lane application? 

 

Thanks,

Jin
