The KS8993F is the industry's first single-chip Fast Ethernet media converter that implements TS-1000 operations, administration, and management (OAM) frames for com-municating link integrity and status between the customer office (CO) and the customer premise equipment (CPE).

Integrating two 10/100 PHYs, three MACs, a Layer 2 managed switch, and a frame buffer in a compact solu-tion, the KS8993F is ideal for use in 100BASE-FX to 10BASE-T or 100BASE-TX conversion in FTTX applica-tions.

The high-performance switching engine supports both QoS and VLAN as well as a full array of management capabilities.

User defined registers (UDRs), another industry first, provide design flexibility and enable low-cost solutions, making the KS8993F an excellent choice for any new media converter design.
