KSZ8463ML/RL/FML/FRL IEEE 1588 Precision Time Protocol Enabled, Three-Port, 10/100-Managed Switch with MII or RMII Revision 1.0 General Description The KSZ8463 ETHERSYNCH™ product line consists of IEEE 1588v2 enabled Ethernet switches, providing integrated munications 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 (i.e., star-wired) 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) - KSZ8463RL: Reduced Media Independent Interface (RMII) - KSZ8463FML: MII, supports 100BASE-FX fiber in addition to 10/100BASE-TX copper - KSZ8463FRL: RMII, 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 munication 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. plementing 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. ETHERSYNCH™ The KSZ8463 product line is built upon Micrel’s industryleading Ethernet technology, with Features designed to offload host processing and streamline your overall design. - Wire-speed Ethernet switching fabric with extensive filtering - Two...
