DM9106EP Product Brief

Three Port Ethernet Switch Controller with 32-bit

PCI Interface

March 2009 Rev.1.0

The DM9106 is a fully integrated and cost-effective fast Ethernet switch

controller with two ports 10M/100M PHY, one port MII/RMII/RGMII interface,

and PCI bus interface. The controller provides basic Layer-2 switch functions

and advance IEEE 802.1Q VLAN, priority queuing scheme, IGMP snooping

protocol. The integrated two ports PHY are compliant with IEEE 802.3u

standards. The MII/RMII/RGMII interface provides the flexibility to connect

Ethernet 10/100/1000M PHY devices. The DM9106 provides direct interface to

the PCI bus. The PCI bus mode is fully complies with PCI 2.2 spec. and

supports bus master mode to achieve the high performance.
