Integrated 3-Port 10/100 Managed Integrated 3-Port 10/100 Managed
The KS8993M, 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 KS8993M 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 on-chip frame buffer memory.
Both PHY units support 10BASE-T and 100BASETX. In addition, one of the PHY unit supports 100BASE-FX.
The KS8993ML is the single supply version with all the identical rich features of the KS8993M.
• Proven Integrated 3-Port 10/100 Ethernet Switch
– 2nd generation switch with three MACs and two PHYs fully compliant to IEEE 802.3u standard
– Non-blocking switch fabric assures fast packet
delivery by utilizing a 1K MAC address lookup table and a store-and-forward architecture
– Full duplex IEEE 802.3x flow control (pause) with force mode option
– Half-duplex back pressure flow control
– Automatic MDI/MDI-X crossover with disable and enable option
– 100BASE-FX support on port 1
– MII interface supports both MAC mode and PHY mode
– 7-wire serial network interface (SNI) support for legacy MAC
