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.

Applications

• Industrial Ethernet end-device attachments for both distributed and

centralized topologies

• Daisy Chained 1588 networks
