Industrial Temperature

Rated USB 2.0 High-Speed

2-Port Hub Controller

Datasheet

PRODUCT FEATURES

Programmable USB signal drive strength. Recover

USB signal integrity due to compromised system

environment using 2-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

Indicate the maximum current that the 2-port hub

consumes from the USB upstream port

Indicate the maximum current required for the hub

controller

General Description

The SMSC 2-Port Hub is a low power, OEM

configurable, STT (Single transaction translator) hub

controller IC with 2 downstream ports for embedded

USB solutions. The 2-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 2-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

Pin Selectable Options for Default Configuration

Hub Controller IC with 2 downstream ports

Enhanced OEM configuration options available

through either a single serial I²C EEPROM, or

SMBus Slave Port

—

Select Downstream Ports as Non-Removable Ports

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

36-pin (6x6mm) QFN lead-free, RoHS compliant

package

Supports industrial temperature range of -40ºC - 85ºC

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, 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.

Programmable USB differential-pair pin location.

Ease PCB layout by aligning USB signal lines directly

to connectors
