Description
AI
The KSZ9567 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. The SGMII port may interface to a fiber optic transceiver.
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.
As a member of the EtherSynch® product family, the KSZ9567 incorporates full hardware support for the IEEE 1588v2 Precision Time Protocol (PTP), including hardware time-stamping at all PHY-MAC interfaces, and a high-resolution hardware "PTP clock". IEEE 1588 provides sub-microsecond synchronization for a range of industrial Ethernet applications.
The KSZ9567 fully supports time-stamping and time-keeping features support IEEE 802.1AS time synchronization. All ports feature credit based traffic shapers for IEEE 802.1Qav, and a time aware scheduler as proposed for IEEE 802.1Qbv.
An assortment of power-management features including Energy-Efficient Ethernet (EEE) have been designed in to satisfy energy efficient environments.
