Cypress Semiconductor CYUSB3304-68LTXI, USB Controller, 4-Channel, 5Gbit/s, USB 2.0, USB 3.0, 1.2 V, 3.3 V, 68-Pin QFN

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
