A five-port, Layer 2 controlled switch with many features aimed at lowering system costs is the KSZ8895MQX. It provides high-performance memory bandwidth and shared memory-based switch fabric with non-blocking setup and is designed for power-constrained 10/100Mbps five-port switch systems with on-chip termination and internal core power controllers. Power management, programmable rate limits and priority ratios, tag/port-based VLAN, packet filtering, fourqueue QoS prioritizing, administration interfaces, and MIB counters are just a few of its many features. When Port 5 is set up to divide MAC5 with SW5-MII/RMII and PHY5 with P5-MII/RMII interfaces, the KSZ8895 family offers various CPU data interfaces to efficiently address both existing and emerging fast Ethernet applications.
