KS8995MA

Product Summary

The KS8995MA 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/port-based 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 KS8995MA contains five 10/100 transceivers with 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. All PHY units support 10BASE-T and 100BASE-TX. In addition, two of the PHY units support 100BASE-FX (ports 4 and 5). Applications are (1)Broadband gateway/firewall/VPN; (2)Integrated DSL or cable modem multi-port router; (3)Wireless LAN access point plus gateway; (4)Home networking expansion; (5)Standalone 10/100 switch; (6)Hotel/campus/MxU gateway; (7)Enterprise VoIP gateway/phone; (8)FTTx customer premise equipment; (9)Managed media converter.
