The KSZ8462 EtherSynch® product line consists of IEEE 1588v2-enabled Ethernet switches, providing integrated communications and synchronization for a range of industrial Ethernet applications. A flexible 8- or 16−bit general bus interface is provided for interfacing to an external host processor.

The KSZ8462 EtherSynch product enables distributed, daisy−chained topologies preferred for Industrial Ethernet networks. Conventional centralized (i.e., star−wired) topologies are also supported for dual−homed, fault tolerant arrangements.

The KSZ8462 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 Microchip's chip driver.Read more
