PRODUCT FEATURES

USB2514

USB 2.0 High-Speed

4-Port Hub Controller

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)

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
