USB2422 2-Port USB 2.0 Hi-Speed Hub Controller General Description Highlights The Microchip USB2422 hub is a low-power, single High performance, low-power, small footprint hub transaction translator, hub controller IC with two down- controller IC with two downstream ports stream ports for embedded USB solutions. The hub Fully compliant with the USB 2.0 Specification controller can attach to an upstream port as a Hi-Speed Optimized for minimal bill-of-materials and low- and Full-Speed hub or as a Full-Speed only hub. The cost designs hub supports Low-Speed, Full-Speed, and Hi-Speed (when configured as a Hi-Speed hub) downstream Applications devices on the enabled downstream ports. LCD monitors and TVs All required resistors on the USB ports are integrated into the hub. This includes all series termination resis- Multi-function USB peripherals tors on D+ and D- pins and all required pull-down and PC motherboards pull-up resistors on D+ and D- pins. The over-current Set-top boxes, DVD players, DVR/PVR sense inputs for the downstream facing ports have Printers and scanners internal pull-up resistors.
