As a fast Ethernet switch, the DM8603 consists of two PHY ports and a port with either MII or RMII interface. As the DM8603 was designed with our customers’ requirements in mind, the switch has built-in versatility and is specifically designed for various data, voice, and video applications needs. The two PHY ports on the DM8603 are IEEE 802.3/u standards compliant. Aside for the first two PHY ports and in an effort for maximum application flexibility, the other port on the DM8603 offer the options to either connect with an Ethernet PHY, reversed MII, or RMII. The reversed MII configuration is used to connect with SoC’s with a MII interface. The RMII interface is the alternative interface configuration in case of the need to connect a lower pin count Ethernet PHY or SoC. To maximize the performance of each port, the DM8603 was designed with many features in mind. For proper bandwidth, each port also supports ingress and/or egress rate control. In support of efficient packet forwarding, the DM8603 has port-based VLAN with tag/un-tag functions for up to 16 groups of 802.1Q. Each Preliminary Version: 1.0 2010/6/14 1 DM8603 10/100 Mbps 3 - port Ethernet Switch Controller With MII / RMII Interface port includes MIB counters, port security, loop-back capability, IGMP snooping, and the build in memory self test (BIST) for system and board level diagnostic. In designing for the requirements of various data, voice, and video applications, enough internal memory has been provided for usage of the DM8603’s three ports, and the internal memory supports an up to 1K uni-cast MAC address table. Then to meet the demands of various bandwidth and latency issues in data, voice, and video applications, each port of the DM8603 has four priority transmit queues. These queues can be defined either through port-based operation, 802.1p VLAN, or the IP packet TOS field automatically. 4.
