TIDA-00287

Design files

Overview

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

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
