The KSZ8441 product is an IEEE 1588v2-enabled Ethernet controller device with an internal MAC and PHY that provides integrated communication and synchronization for a range of industrial Ethernet applications.

The KSZ8441 product enables end-point connection in a centralized topology. A flexible 8-bit or 16-bit interface is provided for interfacing to an external host processor.

The KSZ8441 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 input/output (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
