USB2512 USB 2.0 High-Speed 2-Port Hub Controller Datasheet PRODUCT FEATURES Programmable USB signal drive strength. Recover General Description USB signal integrity due to compromised system The SMSC 2-Port Hub is a low power, OEM environment using 2-level driving strength resolution configurable, STT (Single transaction translator) hub Select the presence of a permanently hardwired USB controller IC with 2 downstream ports for embedded peripheral device on a port by port basis USB solutions. The 2-port hub is fully compliant with the Configure the delay time for filtering the over-current USB 2.0 Specification and will attach to an upstream sense inputs port as a Full-Speed Hub or as a Full-/High-Speed Hub. Configure the delay time for turning on downstream The 2-Port Hub supports Low-Speed, Full- Speed, and port power High-Speed (if operating as a High-Speed Hub) Indicate the maximum current that the 2-port hub downstream devices on all of the enabled downstream consumes from the USB upstream port ports. Indicate the maximum current required for the hub controller General Features Pin Selectable Options for Default Configuration Hub Controller IC with 2 downstream ports Select Downstream Ports as Non-Removable Ports Enhanced OEM configuration options available 2 through either a single serial I C EEPROM, or Applications SMBus Slave Port LCD monitors and TVs 36-pin (6x6mm) QFN lead-free, RoHS compliant Multi-function USB peripherals package PC mother boards Hardware Features Set-top boxes, DVD players, DVR/PVR Printers and scanners Low power operation PC media drive bay Full Power Management with individual or ganged Portable hub boxes power control of each downstream port Mobile PC docking On-chip Power On Reset (POR) Embedded systems Internal 1.8V Voltage Regulator Fully integrated USB termination and Pull-up/Pull- down resistors On Board 24MHz Crystal Driver, Resonator or External 24MHz clock input Enhanced EMI rejection and ESD protection performance OEM Selectable Features Customize Vendor ID, Product ID, and Device ID Select whether the hub is part of a compound device (When any downstream port is permanently hardwired to a USB peripheral device, the hub is part of a compound device) Flexible port mapping and disable sequence. Ports can be disabled/reordered in any order to support multiple product SKUs. Hub will automatically reorder the remaining ports to match the Host controller s numbering scheme.
