General Description
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- or 16-bit general 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 Micrel’s chip
driver.
ETHERSYNCH™
The KSZ8441 is built upon Micrel’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.
