Single-chip Switched Ethernet Controllers for
10 and 10/100Base-X
- Provides packet switching functions between
eight or 12 Ethernet ports and two Auto-
Negotiated on-chip Fast Ethernet ports
- Switch expansion via Fast MII port
Three versions for different cost/performance
points
- GT-48212: 12 10BaseT ports, two 100BaseX
ports and advanced management features
- GT-48208: eight 10BaseT ports, two 100BaseX
ports and advanced management features
- GT-48207: eight 10BaseT ports, two 100BaseX
ports with no management features
Low-cost 32-bit CPU interface for
management
