KSZ8995FQ Product Brief Integrated 5-Port 10/100 Managed Switch Description The KS8995FQ is a highly integrated Layer 2 managed switch with optimized bill of materials (BOM) cost for low port count, cost-sensitive 10/100Mbps switch systems. It also provides an extensive feature set such as tag/portbased VLAN, quality of service (QoS) priority, management, MIB counters, dual MII interfaces and CPU control/data interfaces to effectively address both current and emerging fast Ethernet applications. The KZS8995FQ contains five 10/100 transceiverswith patented mixed-signal low-power technology, five media access control (MAC) units, a high-speed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory. KSZ8995FQ supports 10BASE-T and 100 BASE-TX on port 1, 2, and 5 and 100BASE-FX on port 3, 4. ___________________________________________________________________________________________________________ Block Diagram Micrel, Inc.
