User’s Guide
TPS65988 Evaluation Module
ABSTRACT
This document is the user guide for the TPS65988 Evaluation Module (TPS65988EVM). The TPS65988EVM
allows for evaluation of the TPS65988 IC as part of a stand-alone testing kit and for development and testing of
USB Type-C and Power Delivery (PD) end products. Out of the box, the TPS65988EVM is configured to emulate
a dual-port laptop computer. Both ports can be used to source or sink power, and both are dual-role ports (DRP)
but only support data as a downstream-facing port (DFP) host. When different configurations are required to test
your system, use the
TPS65988 Application Configuration
software tool to create a configuration or load a
different configuration template (see
). The TPS65988EVM uses a control MUX (HD3SS3412) to route
DisplayPort
™
(DP) and a USB HUB (TUSB8020) to route USB signals to the appropriate port A or port A (port
A/B). The control MUX and USB HUB are connected to a SuperSpeed (SS) MUX (TUSB546) which routes the
appropriate DP lanes and USB 3.0 signals according to cable orientation and
Alternate Mode
selection.
