General part information
CYUSB3312-88LTXI
CYUSB3312-88LTXI is a family of USB 3.0 hub controller 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 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 HX3 USB 3.0 Hub.
