Device Overview

Summary

The KSZ9893 is a fully integrated layer 2, managed, three-port gigabit Ethernet switch with numerous advanced features. Two of the three ports incorporate 10/100/1000 Mbps PHYs. The other port has interfaces that can be configured as RGMII, MII or RMII. This port may connect directly to a host processor or to an external PHY.

Full register access is available by SPI or I2C interfaces, and by optional in-band management via any of the data ports. PHY register access is provided by a MIIM interface.

Security features include support for IEEE 802.1X port-based authentication and Access Control List (ACL) filtering.

An assortment of power-management features including Energy-Efficient Ethernet (EEE) have been designed in to satisfy energy efficient environments.
