1 Introduction

This application note shows the cable length extensions allowed by using the TUSB564-Q1 redriver or MUX in a USB Type-C signal path.

USB signal quality measurements are taken on systems of differing channel lengths with the TUSB564-Q1 in the signal path. The data from these measurements demonstrate how a redriver or MUX like the TUSB564-Q1 can drive USB and DP signals across long cables.

For device (sink) applications, the TUSB564-Q1 enables a USB or DP compliant system to pass both USB or DP transmitter electrical compliance and USB receiver jitter tolerance tests.
