Datasheet

PRODUCT FEATURES

USB 2.0 Compatible 4-Port Hub with two upstream

host port connections

Enhanced configuration options available through

either a Single Serial I²C EEPROM, or SMBus Slave

—

Provides electronic reconfiguration and re-assignment

of any of its 4 downstream ports to either of two

upstream host ports (“on-the-fly”).

Allows multiple USB hosts to share peripherals and

enables a user to dynamically assign host ownership.

– Embedded Mode - 8 (predefined, OEM

programmable) configurations for port

assignment are selectable via three external

control signals.

– Peripheral Mode - Dedicated select pin for

every downstream port (total of 4), selectable

edge or level triggered in order to support a

wide range of possible switch configurations

and styles.

Each host has a dedicated Single Transaction

Translator (Single-TT) for supporting FS/LS devices, or

can also operate in Multi-TT mode where each

downstream port has a dedicated Transaction

Translator.

Port

— VID/PID/DID

— Port Configuration

—

String Descriptors (each can support a maximum length

of 31 characters)

– Custom Manufacturer String

– Custom Product String

– Custom Serial String

—

Assignment of downstream ports to upstream hosts

Switching mechanism selection

Hardware Strapping options allow for configuration

without an external EEPROM or SMBus Host

—

Default VID/PID/DID, allows functionality when

configuration EEPROM is absent

—

Complete USB Specification 2.0 Compatibility

—

Includes USB 2.0 Hi-Speed Transceivers

High-Speed (480Mbits/s), Full-Speed (12Mbits/s) and

Low-Speed (1.5Mbits/s) compatible

—

Full power management with choice of Individual or

Ganged power control

Downstream ports can be disabled or defined as non-

removable

On-Board 24MHz Crystal Driver Circuit or 24 MHz

external clock driver

Switching hub can be configured as compound

device for support of ‘embedded’ USB peripherals

Internal PLL for 480MHz USB 2.0 Sampling

Internal 1.8V Linear Voltage Regulator

Multiple LED modes for maximum implementation

flexibility

—

Integrated USB termination and Pull-up/Pull-down

resistors

USB Mode - 2 Single-color LEDs for each downstream

port (total of 8 LEDs).

Internal Short Circuit protection of USB differential

signal pins

—

Host Ownership Mode - 8 Single-Color LEDs indicate

which upstream host each of the downstream ports are

assigned to.

Host Ownership & Port Speed Mode - 8 Dual-Color

LEDs are used to indicate which upstream host each of

the downstream ports are assigned to, while

simultaneously indicating downstream port connection

speed.

1.8 Volt Low Power Core Operation

—

3.3 Volt I/O with 5V Input Tolerance

56-Pin QFN Lead-free RoHS Compliant Package
