LAN9514/LAN9514i
USB 2.0 Hub and 10/100
Ethernet Controller
PRODUCT FEATURES
Datasheet
Highlights
„ Four downstream ports, one upstream port
— Four integrated downstream USB 2.0 PHYs
— One integrated upstream USB 2.0 PHY
„ Integrated 10/100 Ethernet MAC with full-duplex
support
„ Integrated 10/100 Ethernet PHY with HP Auto-MDIX
„ Implements Reduced Power Operating Modes
