Status: In Production
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 the IEEE family of audio video bridging (AVB) standards, which provide for high quality of service (QoS) for latency sensitive traffic streams over Ethernet. 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.

The evaluation board for the KSZ9477S 7-Port Gigabit Ethernet Switch (also KSZ9567 and KSZ8567). The SAMA5D3 processor manages the switch and includes the ATECC508A security encoder. The DSC1101 is the reference clock for GigE communication. The EVB can be used to implement IEEE 1588v2, AVB and DLR/HSR (available on KSZ9477 only) network redundancy.
