Highlights

• Integrated USB 2.0 Compatible 2-Port Hub

-

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

(12Mbits/s) and Low-Speed (1.5Mbits/s)

compatible

- Full power management with ganged 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
