The DM8108 is an 8 port 10/100Mbit/s nonblocking Ethernet switch with on-chip address-lookup engine. The DM8108 provides a low-cost, high-performance switch solution with PHYs and single SGRAM. The DM8108 provides eight 10/100Mbit/s Fast Ethernet interface. In half-duplex mode, all ports support backpressure capability to reduce the risk of data loss for a long burst of activity. In the full-duplex mode of operation, the device uses IEEE std. 802.3 frame-based pause protocol for flow control. With full-duplex capability, port 0 7 support 1.6Gbit/s aggregate bandwidth connections. The DM8108 also supports port trunking/load balancing on the
