KSZ8993MI Datasheet

Ethernet ICs


The KSZ8993MI a highly integrated Layer 2 managed switch, is designed for low port count, cost-sensitive 10/100 Mbps switch systems. It offers an extensive feature set that includes tag/port-based VLAN, quality of service (QoS) priority, management, management information base (MIB) counters, MII/SNI, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications. The KSZ8993M contains two 10/100 transceivers with patented mixed-signal low-power technology, three media access control (MAC) units, a highspeed non-blocking switch fabric, a dedicated address lookup engine, and an on-chip frame buffer memory. Both PHY units support 10BASE-T and 100BASETX. In addition, one of the PHY unit supports 100BASE-FX. The KSZ8993ML is the single supply version with all the identical rich features of the KSZ8993M.
