PRODUCT FEATURES

LAN9512

USB Hub with Integrated

10/100 Ethernet Controller

Highlights

„

Two downstream ports, one upstream port

— Two 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

„

Minimized BOM Cost

— Single 25 MHz crystal (Eliminates cost of separate

crystals for USB and Ethernet)

— Built-in Power-On-Reset (POR) circuit (Eliminates

requirement for external passive or active reset)

Target Applications

„

Desktop PCs

„

Notebook PCs

„

Printers

„

Game Consoles

„

Embedded Systems

„

Docking Stations
