USB2514 USB 2.0 High-Speed 4-Port Hub Controller Datasheet PRODUCT FEATURES Flexible port mapping and disable sequence. Ports General Description can be disabled/reordered in any order to support The SMSC 4-Port Hub is low power, OEM configurable, multiple product SKUs. Hub will automatically reorder MTT (multi transaction translator) hub controller IC with the remaining ports to match the Host controller s 4 downstream ports for embedded USB solutions. The numbering scheme 4-port hub is fully compliant with the USB 2.0 Programmable USB differential-pair pin location Specification and will attach to an upstream port as a Ease PCB layout by aligning USB signal lines directly Full-Speed Hub or as a Full-/High-Speed Hub. The 4- to connectors Port Hub supports Low-Speed, Full-Speed, and High- Programmable USB signal drive strength. Recover Speed (if operating as a High-Speed Hub) downstream USB signal integrity due to compromised system devices on all of the enabled downstream ports. environment using 4-level driving strength resolution Select the presence of a permanently hardwired USB General Features peripheral device on a port by port basis Hub Controller IC with 4 downstream ports Configure the delay time for filtering the over-current High-performance multiple transaction translator sense inputs MultiTRAK Technology Provides one transaction Configure the delay time for turning on downstream translator per port port power Enhanced OEM configuration options available Configure the polarity of downstream port power through either a single serial i2C EEPROM, or control signals SMBus Slave Port Indicate the maximum current that the 4-port hub 36-pin (6x6mm) and 48-Pin (7x7mm) QFN lead-free, consumes from the USB upstream port RoHS compliant packages Indicate the maximum current required for the hub Footprint compatible with USB2513 and USB2512 controller (36-pin QFN) to provide designers with flexibility Supports Custom String Descriptor up to 31 regarding the quantity of USB expansion ports characters in length for: utilized without redesign Product String Hardware Features Manufacturer String Serial Number String Low power operation Full Power Management with individual or ganged Pin Selectable Options for Default Configuration power control of each downstream port Select Downstream Ports as Non-Removable Ports On-chip Power On Reset (POR) Select Downstream Ports as Disabled Ports Internal 1.8V Voltage Regulator Select Downstream Port Power Control and Over- Fully integrated USB termination and Pull-up/Pull- Current Detection on a Ganged or Individual Basis down resistors Select Downstream Port Power Control Polarity On Board 24MHz Crystal Driver, Resonator or Select USB Signal Drive Strength External 24/48MHz clock input Select USB Differential Pair Pin location USB host/device speed indicator.
