KSZ9897RTXC Network Controllers by Microchip Technology
7-Port Gigabit Ethernet Switch with SGMII/RGMII/MII/RMII
| Status: | Active |
|---|---|
| Series: | KSZ9897 |
| RoHS: | Compliant |
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.
An assortment of power-management features including Energy-Efficient Ethernet (EEE) have been designed in to satisfy energy efficient environments.
