USB2517 USB 2.0 Hi-Speed 7-Port Hub Controller Datasheet PRODUCT FEATURES General Description Flexible port mapping and disable sequence. Ports can be disabled/reordered in any order to support The SMSC 7-Port Hub is a low power, OEM multiple product SKUs. Hub will automatically reorder configurable, MTT (multi transaction translator) hub the remaining ports to match the Host controller s controller IC with 7 downstream ports for embedded numbering scheme USB solutions. The 7-port hub is fully compliant with the Programmable USB differential-pair pin location USB 2.0 Specification and will attach to an upstream Eases PCB layout by aligning USB signal lines directly port as a Full-Speed Hub or as a Full-/Hi-Speed Hub. to connectors The 7-Port Hub supports Low-Speed, Full-Speed, and Programmable USB signal drive strength.
