The KS8995M is a highly integrated layer-2 managed switch with optimized BOM (Bill-Of-Materials) cost for low port count, cost-sensitive 10/100Mbps switch systems. It also provides an extensive feature set such as tag/port-based VLAN, QoS priority, management, MIB counters, dual MII interface and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications. The KS8995M contains five 10/100 transceivers with patented mixed-signal low-power technology, five MAC (Media Access Control) units, a high-speed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory. All PHY units support 10Base-T and 100BaseTX. In addition, two of the PHY units support 100BaseFX (Ports 4 & 5).
