7 Summary

The TUSB564-Q1 is designed to recover USB and DisplayPort signals that travel over long cable lengths or lossy channels. This is beneficial for applications which require high signal integrity across long distances. In the test systems used for this application note, the TUSB564-Q1 allows USB signals to pass over 9 meter cable lengths and DisplayPort signals to pass over 9.2 meter cable lengths. This device can be used in USB-C Alt mode systems to prevent attenuation and signal quality issues that stem from insertion loss. This document is intended to show the system-level impact of the TUSB564-Q1 when driving signals over a long channel.
