KSZ9897中文资料7-Port Gigabit Ethernet Switch with SGMII/RGMII/MII/RMII数据手册Microchip规格书

描述 Description

The KSZ9897 is a fully integrated layer 2, managed,seven-port gigabit Ethernet switch with numerousadvanced features. Five of the seven ports incorporate10/100/1000 Mbps PHYs. The other two ports haveinterfaces that can be configured as SGMII, RGMII, MII or RMII.Either of these may connect directly to a host processor orto 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 includingEnergy-Efficient Ethernet (EEE) have been designed in tosatisfy energy efficient environments.
