Microchip’s KSZ9567 / 9897 family of 7-port gigabit Ethernet switches are fully integrated, 2-layer, managed, and have 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. The SGMII port on the KSZ9567 may interface to a fiber optic transceiver.
Registers are fully accessible via SPI or I2C interfaces and by optional in-band management using any of the data ports. PHY register access is provided by a MIIM interface. KSZ9567 / 9897 products have several security features including support for IEEE 802.1X port-based authentication and access control list (ACL) filtering. KSZ9567 products are a part of the EtherSynch® product family so full hardware support for IEEE 1588v2 precision time protocol (PTP) is included. An assortment of power-management features including energy-efficient Ethernet (EEE) have been designed-in to satisfy energy efficient environments.
