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
