KSZ8463FMLI

The KSZ8463 ETHERSYNCH™ product line consists of IEEE 1588v2 enabled Ethernet switches, providing integrated communications and synchronization for a range of Industrial Ethernet applications. The KSZ8463 ETHERSYNCH product line enables distributed, daisy-chained topologies preferred for Industrial Ethernet networks. Conventional centralized topologies are also supported for dualhomed, fault-tolerant arrangements. A flexible set of standard MAC interfaces is provided to interface to external host processors with embedded Ethernet MACs KSZ8463ML Media Independent Interface (MII) KSZ8463FML MII, supports 100BASE-FX fiber in addition to 10/100BASE-TX copper. The KSZ8463 devices incorporate the IEEE 1588v2 protocol. Sub-microsecond synchronization is available via the use of hardware-based time-stamping and transparent clocks making it the ideal solution for time synchronized Layer 2 communication in critical industrial applications. Extensive general purpose I/O (GPIO) capabilities are available to use with the IEEE 1588v2 PTP to efficiently and accurately interface to locally connected devices. Complementing the industry’s most-integrated IEEE 1588v2 device is a precision timing protocol (PTP) v2 software stack that has been pre-qualified with the KSZ84xx product family. The PTP stack has been optimized around the KSZ84xx chip architecture, and is available in source code format along with Micrel’s chip driver. The KSZ8463 product line is built upon Micrel’s industryleading Ethernet technology, with features designed to offload host processing and streamline your overall design.

Management Capabilities The KSZ8463ML/RL/FML/FRL includes all the functions of a 10/100BASE-T/TX/FX switch system which combines a switch engine, frame buffer management, address look-up table, queue management, MIB counters, media access controllers (MAC) and PHY transceivers Non-blocking store-and-forward switch fabric assures fast packet delivery by utilizing 1024 entry forwarding table Port mirroring/monitoring/sniffing: ingress and/or egress traffic to any port MIB counters for fully-compliant statistics gathering - 34 counters per port Loopback modes for remote failure diagnostics Rapid spanning tree protocol support (RSTP) for topology management and ring/linear recovery Bypass mode, which ensure continuity even when a Host is disabled or fails Robust PHY Ports Two integrated IEEE 802.3/802.3u-compliant Ethernet transceivers supporting 10BASE-T and 100BASE-TX Copper and 100BASE-FX fiber mode support in the KSZ8463FML and KSZ8463FRL Copper mode support in the KSZ8463ML and KSZ
