This schematic checklist provides a brief explanation of the TUSB1004 and TUSB1142 device pin and the recommended configuration of the device pins for default operation. The TUSB1004 is a 10 Gbps USB 3.2 quad channel linear redriver for USB Type-A application. The TUSB1142 is a 10 Gbps USB 3.2 linear redriver with 1:2 DeMUX or 2:1 Mux function for USB-C™ application. This document is intended to aid design at the system level for general applications but should not be the only resource used. In addition to this list, customers are advised to use the information in the TUSB1004 data sheet [1], TUSB1142 data sheet [3], the EVM User's Guides [2] [4] and associated documents to gain a full understanding of device functionality
