2-Port USB 2.0 Hub Controller
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
• Default VID/PID/DID, allows functionality when
configuration EEPROM is absent
• Hardware Strapping options allow for configura-
tion without an external EEPROM or SMBus Host
• On-Board 24MHz Crystal Driver Circuit or 24 MHz
external clock driver
• Internal PLL for 480MHz USB 2.0 Sampling
• Internal 1.8V Linear Voltage Regulator
• Integrated USB termination and Pull-up/Pull-down
resistors
• Internal Short Circuit protection of USB differential
signal pins
• Basic single-color LED support
• 1.8 Volt Low Power Core Operation
• 3.3 Volt I/O with 5V Input Tolerance
• 36-Pin QFN or 48-Pin TQFP RoHS compliant
package
