USB Type-C Plug to USB Type-A Receptacle SuperSpeed MUX With UFP Controller Reference Design

Texas Instruments

The TIDA-00891 is designed to evaluate HD3SS3220 devices for UFP implementations. This reference design can also be used as a hardware reference design for any implementation using the HD3SS3220 with a USB-C™ connector. Reference design files can be provided upon request to aid PCB design with HD3SS3220. The layout files can be used as a guideline to implement the TUSB321A with illustrations of the routing/placement rules. The reference design includes on-board USB Type-A plug to connect legacy USB systems. Please note that the reference design may include test components for evaluation purposes not applicable for production.
