Description
General part information
KSZ9897 Series
The KSZ9897 is a fully integrated layer 2, managed, seven-port gigabit Ethernet switch with numerous advanced features. Five of the seven ports incorporate 10/100/1000 Mbps PHYs. The other two ports have interfaces that can be configured as SGMII, RGMII, MII or RMII. Either of these 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.
