4 Port USB 3.0 Hub Reference Design

TIDA-00288

Design files

Overview

This verified reference design is a four-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 and overcurrent protection.

Features
  • Complete four port USB 3.0 compliant hub
  • Supports individual port power control
  • ESD protection on both upstream and downstream ports
  • Operates as a bus-powered device or from an external power source.
  • Supports operation as an USB3.0 and USB2.0 device
  • 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.
