2.1 Standard USB Type-C Application
The parts covered in this application cannot support DisplayPort Alt. Mode and are typically used to connect a single USB 3.2 TX/RX pair to a USB Type-C connector. All parts in this section have a signal conditioning component.
-
USB 3.2 Gen 1 (5Gbps)
- TUSB542/ TUSB521-Q1
The TUSB542 and the automotive qualified version, TUSB521-Q1, are both active 2:1 MUXs designed for USB signals. An active MUX is an IC that is able to provide the functionality of a MUX and redriver in one chip. These parts can be used as a loss reducing component in standard USB3.2 Gen 1 systems. Additionally, the parts both are able to take a standard USB TX and RX pair and path these signals out to a USB Type-C connector.
Figure 2-1 Typical USB Type-C Application for
TUSB542 or TUSB521-Q1- TUSB544
The TUSB544 is a 4-lane redriver that is able to provide equalization. This redriver is designed so part can also be used for DisplayPort Alt. Mode systems as well as standard USB Type-C systems. This part has directional control for equalization, so the part can be customized for various applications. For best results, place the TUSB544 after the USB Type-C MUX, and this is usually placed close to the USB Type-C connector.

USB 3.2 Gen 2 (10Gbps)
- TUSB1042/ TUSB1142/ TUSB1021-Q1
The TUSB1042 and the automotive qualified version, TUSB1021-Q1, are both active 2:1 MUXs designed for USB signals. An active MUX is an IC that is able to provide the functionality of a MUX and redriver in one chip. These parts can be used as a loss reducing component in standard USB3.2 Gen 1 systems. The TUSB1142 has the same functionality of the TUSB1042 and TUSB1021-Q1, but adds the convenience of adaptive EQ on the USB Type-C signals. This adaptive EQ automatically compensates the signal removing the need for EQ tuning. Additionally, all three are able to take a standard USB TX and RX pair and path these signals out to a USB Type-C connector.
Figure 2-3 Typical USB Type-C Application for
TUSB1042, TUSB1021-Q1, or TUSB1142- TUSB1044/ TUSB1044A
The TUSB1044 and TUSB1044A are 4-lane redrivers that are able to provide equalization. These redrivers are designed to be used for DisplayPort Alt. Mode systems as well as standard USB Type-C systems. These parts have directional control for the parts equalization, so the parts can be customized for various applications. For best results, place the TUSB1044 and TUSB1044A after the USB Type-C MUX, and usually placed close to the USB Type-C connector.
