IEEE 1588 protocol software with new features
for the telecommunication sector

The IEEE 1588 protocol software from IXXAT enables networking devices with accurate and reliable time synchronization for automation, automotive, measurement and telecommunication applications. Depending on the microcontroller system and the type of network employed, IXXAT’s IEEE 1588-2008 PTP software is able to attain time synchronization accuracy in the nanosecond range.

The new version 1.05 now supports the basic requirements of the ITU-T G.8265.1 telecom specification for “Packet Timing Signal Fail Mechanism”, “Multi Clock” and “One Way” mode making it an optimal solution for use in telecom applications.

IXXAT and SoC-e offer a complete IEEE 1588 solution for Xilinx FPGAs.

IXXAT Automation and System on Chip engineering (SoC-e) Bilbao in Spain started a cooperation on IEEE 1588 in the beginning of 2011. By combining SoC-e’s IP core for Xilinx FPGAs and IXXAT’s field-proven PTP protocol software, a new powerful IEEE 1588 solution was created. SoC-e’s customers can now benefit from IXXAT’s PTP software, which is designed for highly accurate synchronization applications. The protocol software is field-proven in a wide range of applications while being comprehensively supported and maintained by IXXAT.

for the telecommunication area and AVB networks

Many applications, in the telecommunication sector, in AVB networks as well as in the measurement and automation area, require a highly accurate time synchronization of the individual nodes in the system.

The IEEE 1588 Precision Time Protocol (PTP), which is offered by IXXAT as protocol software package, enables the synchronization of nodes, which are connected e.g. via Ethernet. To achieve a highly accurate synchronization in the sub-microsecond range, however, in addition to the protocol software a hardware support is required to provide a highly accurate clock and to assign time stamps to the messages.

New features and extended hardware support

The precise time synchronization of devices in distributed applications, like measurement, telecommunication and automation systems as well as in the automotive sector, is increasingly becoming an important requirement. The Precision Time Protocol (PTP) according to IEEE 1588 meets this requirement by enabling a highly accurate synchronization of distributed devices over Ethernet down to the nanosecond range.

Thanks to the availability of real-time extensions and low-cost components, Ethernet is increasingly used in automation and metrology. For many automation applications, exact time synchronization of controls, sensors and actuators within a network or even between several networks is vital. One possibility for this is offered by the “Precision Clock synchronization Protocol for Networked Mea-surement and Control Systems” or „Precision Time Protocol” (PTP) for short, which is defined by the IEEE standard 1588. However, the protocol only provides the basis: maximum precision for synchronization requires support from suitable hardware. The following text describes how IEEE 1588 PTP works and what hardware-based solutions are suitable for it…
