USB 2.0 Hi-Speed 7-Port Hub Controller PRODUCT FEATURES Datasheet General Description пЃ® T h e S M S C 7 -P o r t H u b i s a l o w p o w e r, O E M
configurable, MTT (multi transaction translator) hub
controller IC with 7 downstream ports for embedded
USB solutions. The 7-port hub is fully compliant with the
USB 2.0 Specification and will attach to an upstream
port as a Full-Speed Hub or as a Full-/Hi-Speed Hub.
The 7-Port Hub supports Low-Speed, Full-Speed, and
Hi-Speed (if operating as a Hi-Speed Hub) downstream
devices on all of the enabled downstream ports. General Features
