KSZ8993M

KSZ8993F : The Micrel KS8993F is the industry’s first single chip Fast Ethernet Media Converter with built-in OAM functions. The KS8993F integrates three MACs, two PHYs, OAM, frame buffer and high performance switch into a single chip. It is ideal for use in 100BASE-FX to 10BASE-T or 100BASETX conversion in the FTTx market. The KS8993F provides remote loop back and OAM (Operation, Administration and Maintenance) to manage subscriber access network from carrier center side to terminal side. The KS8993F supports advanced features such as rate limiting, force flow control and link transparency. The KS8993F with built-in Layer 2 switch capability will filter packets and forward them to valid destination. I.

KSZ8993ML : 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 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 100BA.
