General Description

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. HX3 includes the following Cypress-proprietary features:

Shared Link™: Enables extra downstream (DS) ports for on-board connections in embedded applications

Ghost Charge™: Enables charging of devices connected to the DS ports when no host is connected on the upstream (US) port
