Product Introduction
The KSZ8993M, 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 a wide range of Fast Ethernet applications.
The KSZ8993M contains two 10/100 transceivers with patented mixed-signal low-power technology, three media access control (MAC) units, a high speed non-blocking switch fabric, a dedicated address lookup engine, and an onchip frame buffer memory.
Both PHY units support 10BASE-T and 100BASE-TX. In addition, one of the PHY unit supports 100BASE-FX.
