KS8993M/ML/MI Product Brief Integrated 3-Port 10/100 Managed Switch with PHY The KS8993M family is a highly integrated Layer 2 managed switch designed for low-port count, cost-sensitive 10/100 Mbps switch systems. It offers an extensive feature set that includes tag/port-based VLAN, QoS priority, switch management, MIB counters, MII/SMI interface, 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 look-up engine, and an on-chip frame buffer memory. Both PHY ports support 10BASE-T and 100BASE-TX with Auto-MDIX for reliable detection of and correction for straight-through and crossover cables. In addition, one PHY port supports 100BASE-FX for managed media converter applications. QoS prioritization, both tag and port-based, makes the KS8993M family ideal for latency critical applications such as Voice over Internet Protocol VoIP phones and industrial Ethernet applications. The KS8993M is available in a wide variety of power supply, packaging, and temperature options to fit the demanding needs of today’s applications. Commercial temperature range 0oC to +70oC Industrial temperature range to +85oC. For additional information, contact your local Micrel Field Application Engineer or salesperson.
