IEEE 1588v2-enabled Ethernet ICs

25 January 2012 Telecoms, Datacoms, Wireless, IoT

Micrel has introduced the KSZ84xx family of IEEE 1588v2-enabled Ethernet devices for Industrial Ethernet and Power Substation Automation applications. The solution employs Micrel’s EtherSynch technology, which integrates IEEE 1588v2 distributed synchronisation, Ethernet switching and precision GPIO in an energy efficient, compact package.

The KSZ84xx platform supports both centralised and distributed network topologies. A full complement of precise timing protocol timing modes are provided, including the transparent clock (TC) introduced in IEEE 1588v2, along with a range of host interfaces capable of interfacing to a wide range of CPUs.

The switches are particularly well suited for distributed network topologies which are preferred for Industrial Ethernet networks. 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.

The KSZ84xx reduces operational power consumption, which is less than 300 mW. Advanced power management features complement the inherently low-power physical layer design, including energy efficient Ethernet (EEE- IEEE 802.3az), wake on LAN (WoL), energy detect power down (EDPD) and software power down.

The KSZ84xx product family consists of the KSZ8463, a 3-port switch with MII/RMII interface; the KSZ8462, a 3-port switch with generic host interface; and the KSZ8441, a controller with generic host interface.

Micrel also intends to offer a pre-qualified precise timing protocol software stack, which has been integrated with the driver and optimised to exploit the KSZ84xx architecture. Source code is available under licence.
