2-Port USB 3.0 hub reference design
TIDA-00287
This product has been released to the market and is available for purchase. For some products, newer alternatives may be available.
See the Important Notice and Disclaimer covering reference designs and other TI resources.
Description
This verified reference design is a two-port, USB 3.0 compliant hub. It provides simultaneous SuperSpeed and high-speed/full-speed connections on the upstream port and provides SuperSpeed, high-speed, full-speed, or low-speed connections on the downstream ports.
The hub design provides power control for each downstream port, as well as over-current protection and ESD protection.
Features
- Complete dual-port USB 3.0 compliant hub
- Bus-powered
- Integrated current limiting
- ESD protection on all ports
- Schematic, layout, test data and design documentation for ease of reuse
