KSZ8567RTXI-TR

KSZ8567RTXI-TR 概要

The KSZ8567 is a fully integrated layer 2, managed,seven-port 10/100 Ethernet switch with numerousadvanced features, designed to exceed Automotive AEC-Q100 Grade 2 (-40°C to +105°C) and EMC requirements . Five of the seven ports incorporate10/100 Mbps PHYs. The other two ports have 1000 Mbps MAC interfaces 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.

As a member of the EtherSynch® product family, theKSZ8567 incorporates full hardware support for the IEEE1588v2 Precision Time Protocol (PTP), including hardwaretime-stamping at all PHY-MAC interfaces, and a high-resolution hardware “PTP clock”. IEEE 1588 provides sub-microsecond synchronization for a range of industrialEthernet applications.

The KSZ8567 fully supports the IEEE family of audiovideo bridging (AVB) standards, which provide for highquality of service (QoS) for latency sensitive traffic streamsover Ethernet. Time-stamping and time-keeping featuressupport IEEE 802.1AS time synchronization. All portsfeature credit based traffic shapers for IEEE 802.1Qav,and a time aware scheduler as proposed for IEEE802.1Qbv.

An assortment of power-management features includingEnergy-Efficient Ethernet (EEE) have been designed in tosatisfy energy efficient environments.
