9 Applications and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The TUSB8043 is a four-port USB 3.1 Gen1 compliant hub. It provides simultaneous SuperSpeed USB and high-

speed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or

low speed connections on the downstream port. The TUSB8043 can be used in any application that needs

additional USB compliant ports. For example, a specific notebook may only have two downstream USB ports. By

using the TUSB8043, the notebook can increase the downstream port count to five.
