Ethernet switching ICs

4 September 2013 Telecoms, Datacoms, Wireless, IoT

Micrel’s KSZ84xx family of IEEE 1588v2-enabled Ethernet devices are designed for Industrial Ethernet and power substation automation applications. The solution employs EtherSynch technology, which integrates IEEE 1588v2 distributed synchronisation, Ethernet switching and precision GPIO in an energy efficient, compact package. The ICs feature a hardware-oriented architecture that reduces the synchronisation and communications processing demands on the host CPU. Such features as source addressing, one-step TC corrections and bypass mode facilitate both ring and linear topologies. By integrating the IEEE 1588 PTPv2 time stamping as close to the physical layer as possible, sub-100 ns synchronisation performance has been demonstrated.
