The KSZ8565 is a managed, five-port 10/100 Ethernet switch with numerous advanced features designed to exceed Automotive AEC-Q100 Grade 2 (-40°C to +105°C) and EMC requirements. Four of the five ports incorporate 10/100 Mbps PHYs. The other port has a 1000 Mbps MAC interface that can be configured as RGMII, MII or RMII. It can 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.

As a member of the EtherSynch® product family, the KSZ8565 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 KSZ8565 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.
