Integrated USB 2.0
Compatible 3-Port Hub
PRODUCT FEATURES
Integrated USB 2.0 Compatible 3-Port Hub
— 3 Transaction Translators for highest performance
— High-Speed (480Mbits/s), Full-Speed (12Mbits/s) and
Low-Speed (1.5Mbits/s) compatible
— Full power management with per port or ganged,
selectable power control
— Detects Bus-Power/Self-Power source and changes
mode automatically
Complete USB Specification 2.0 Compatibility
— Includes USB 2.0 Transceivers
VID/PID/DID, and Port Configuration for Hub via:
— Single Serial I2C EEPROM
— SMBus Slave Port
Default VID/PID/DID, allows functionality when
configuration EEPROM is absent
Hardware Strapping options allow for configuration
without an external EEPROM or SMBus Host
