3-Port Ethernet Switch Controller with PCI Interface DM9106


The DM9106 is a fully integrated, high performance, and cost-effective fast Ethernet switch controller with one general PCI bus interface, two ports 10/100Mbps PHY, and one port MII or RMII interface. Additional features are IGMP v1, v2 snooping, IPv4 and IPv6 support, Port Security, Spanning Tree Protocol and Wake-on-LAN.
Each port of the DM9106 provides four priority transmit queues, that can be defined by port-based, 802.1p VLAN, or IP packet ToS field automatically, to fit the various bandwidth and latency requirement of data, voice, and video applications. Each port also supports ingress and/or egress rate control to provide proper bandwidth. And up to 16 groups of 802.1Q VLAN with Tag/Un-tag functions are supported to provide efficient packet forwarding. The integrated two ports PHY are compliant with IEEE 802.3u standards.
The MII interface provides the flexibility to connect Ethernet PHY, and it can be configured as Reversed MII interface for SoC with MII interface. An alternative interface, the RMII interface, is also provided to connect the lower pin count Ethernet PHY or SoC with RMII interface
