KSZ8893MBL-TR

The KSZ8893MBL, 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 rate limiting, tag/port-based VLAN, QoS priority, management, management information base (MIB) counters, RMII/MII/SNI, and CPU control/data interfaces to effectively address both current and emerging Fast Ethernet applications.

The KSZ8893MBL 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 PHY unit supports 100BASE-FX. The KSZ8893MBL comes in a lead-free package, and is also available in industrial temperature-grade KS8893MQLI/MBLI and Automotive-grade KSZ8893 MQL AM.
