Ethernet Switch
Data Sheet
Features
• 12 10/100Mbps Autosensing, Fast Ethernet ports
with Reduced MII Interface
• Single Gigabit Ethernet port
• Supports both GMII and integrated Physical Coding
Sublayer with Ten Bit Interface (TBI) logic to
interface directly with Gigabit transceivers
• Two-chip solution for 24+2 configuration
- 32-bit wide bi-directional pipe at 100Mhz pro-
vides 6.4Gbps pipe to connect two MDS213 chips
• Supports up to 6.548 Mpps system throughput
using non-blocking architecture
• High performance Layer 2 packet forwarding and
filtering at full wire speed.
• Very low latency through single store and forward
at ingress port and cut-through switching at
destination ports
• Port Trunking and Load Sharing for high
bandwidth links between switches
• On-chip address lookup engine and memory for
up to 2K MAC addresses
• Parallel Flash interface for fast self initialization
• Supports packet filtering and port security
- System wide filtering
- Static MAC destination and source address
filtering
- VLAN for multicast/broadcast filtering
