AN91378 provides hardware design and PCB layout guidelines for HX3, a high-performance USB 3.0 hub. These guidelines will help to ensure best performance with respect to signal integrity and full electrical compliance with the USB 3.0 Specification.

Introduction

HX3 is a family of USB 3.0 hub controllers compliant with the USB 3.0 specification revision 1.0. HX3 supports SuperSpeed (SS), Hi-Speed (HS), Full-Speed (FS), and Low-Speed (LS) on all the ports. It has integrated termination, pull-up, and pull-down resistors, and supports configuration options through pin-straps to reduce the overall BOM of the system.
