Ethernet Product Highlight
IEEE 1588v2 EtherSynch™ Switch for
Industrial Ethernet Networks
Micrel's KSZ84XX family provides effi cient end-device connectivity for
Industrial Ethernet networks, minimizing per-device attachment costs.
The KSZ84XX family features EtherSynch™ technology, blending
IEEE 1588v2 time stamping, precision local clock, synchronized I/O,
and wire-speed Ethernet switching in a compact package. The device
supports leading Industrial Ethernet standards including Ethernet/IP™,
Profi net™, PowerLink™, among others.
Precision GPIO extends synchronization to local devic-
es and allows multiple end devices to share the Industrial
Ethernet attachment. The 12 Precision GPIO are capable of
creating complex waveforms, with multiple GPIO events supported
per pin.
Micrel pre-qualifi ed and optimized the KSZ84XX family to operate with
an optimized Precision Timing Protocol (PTPv2) protocol stack to get up
and running quickly.
The hardware-oriented chip architecture reduces synchronization and
communications processing demands, streamlining the Host CPU.
Micrel features the industry's most robust, and low-power Industrial
Ethernet switches, complemented by advanced physical layer
technology, and power management.
The KSZ84XX family is the ideal choice for real-time, Industrial Ethernet
applications, and ease of integration with Host CPUs.
