PRODUCT FEATURES
General Description
The SMSC 4-Port Hub is low power, OEM configurable,
MTT (multi transaction translator) hub controller IC with
4 downstream ports for embedded USB solutions. The
4-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-/High-Speed Hub. The 4-
Port Hub supports Low-Speed, Full- Speed, and High-
Speed (if operating as a High-Speed Hub) downstream
devices on all of the enabled downstream ports.
General Features
„ Hub Controller IC with 4 downstream ports
„ High-performance multiple transaction translator.
MultiTRAK™ Technology Provides one transaction
translator per port
„ Enhanced OEM configuration options available
through either a single serial i2C EEPROM, or
SMBus Slave Port
„ 36-pin (6x6mm) and 48-Pin (7x7mm) QFN lead-free,
RoHS compliant packages
„ Footprint compatible with USB2513 and USB2512
(36-pin QFN) to provide designers with flexibility
regarding the quantity of USB expansion ports
utilized without redesign
Hardware Features
„ Low power operation
„ Full Power Management with individual or ganged
power control of each downstream port
„ On-chip Power On Reset (POR)
„ Internal 1.8V Voltage Regulator
„ Fully integrated USB termination and Pull-up/Pull-
down resistors
„ On Board 24MHz Crystal Driver or External
24/48MHz clock input
„ USB host/device speed indicator. Per-port 3-color
LED drivers that indicate the speed of USB host and
device connection - hi-speed (480 Mbps), full-speed
(12 Mbps), low-speed (1.5 Mbps) (48-pin QFN)
„ 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)
Datasheet
„ 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
„ Programmable USB differential-pair pin location
„ Ease PCB layout by aligning USB signal lines directly
to connectors
„ Programmable USB signal drive strength. Recover
USB signal integrity due to compromised system
environment using 4-level driving strength resolution
„ Select the presence of a permanently hardwired USB
peripheral device on a port by port basis
„ Configure the delay time for filtering the over-current
sense inputs
„ Configure the delay time for turning on downstream
port power
„ Configure the polarity of downstream port power
control signals
„ Indicate the maximum current that the 4-port hub
consumes from the USB upstream port
„ Indicate the maximum current required for the hub
controller
„ Supports Custom String Descriptor up to 31
characters in length for:
– Product String
– Manufacturer String
– Serial Number String
„ Pin Selectable Options for Default Configuration
— Select Downstream Ports as Non-Removable Ports
— Select Downstream Ports as Disabled Ports
— Select Downstream Port Power Control and Over-
Current Detection on a Ganged or Individual Basis
— Select Downstream Port Power Control Polarity
— Select USB Signal Drive Strength
— Select USB Differential Pair Pin location
— Select on-chip or off-chip voltage regulator mode
Applications
„ LCD monitors and TVs
„ Multi-function USB peripherals
„ PC mother boards
„ Set-top boxes, DVD players, DVR/PVR
„ Printers and scanners
„ PC media drive bay
„ Portable hub boxes
„ Mobile PC docking
„ Embedded systems
