DS90UB933-Q1: Differential impedance clarification

Part Number: DS90UB933-Q1

Hello team,

I have a question about 933-934 application.

https://e2e.ti.com/support/interface/f/interface-forum/965149/ds90ub913a-q1-stp-cable-requirement

In the above thread, the TI expert recommended PCB differential impedance tolerance is 5%.

However,  many PCB manufactures say that it is difficult to guarantee 5% tolerance.

Does TI guarantee the operation if the PCB diff. impedance tolerance is 10%?

Regards,

Itoh
