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-/16-/32-bit or PCI bus 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.
The KSZ8441 is built upon Microchip’s industry-leading Ethernet technology， with features designed-to-offload host processing and streamline overall design， including：
• 1 integrated 10/100BASE-TX PHY transceiver， featuring the industry’s lowest power consumption
• 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
