7 Summary

Due to the higher data rates of USB3 and USB3.1 Gen 2, this is crucial to properly integrate a redriver into a system to make sure that the related signals are properly boosted and do not violate any of the conditions outlined by the USBIF. By following the above configuration guidelines for the TUSB521-Q1 and the TUSB1021-Q1, this can be easy to make sure that the system is able to properly boost the USB3.1 data signals without causing any over or under-compensation. Additionally, by following the layout guidelines here that are typically associated with a USB3.1 trace, designing a system around the harsher requirements of a USB3.1 needs to be much easier to understand.
