KSZ8462

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.

The wire−speed, store−and−forward switching fabric provides a full complement of quality-of-service (QoS) and congestion control features optimized for real−time Ethernet. The KSZ8462 product is built upon Microchip's industry−leading Ethernet technology, with features designed to offload host processing and streamline your overall design:

• Wire−speed Ethernet switching fabric with extensive filtering
• Two integrated 10/100BASE-TX PHY transceivers, featuring the industry’s lowest power consumption
• Full−featured QoS support
• Flexible management options that support common standard interfaces
• A robust assortment of power-management features including energy-efficient Ethernet (EEE) have been designed in to satisfy energy-efficient environments
