In co-operation with STMicroelectronics, IXXAT offers an adapted version of its IEEE 1588-2008 protocol software for the STM3220F-EVAL Evaluation board. The software as binary code is available for download and thus enables a quick and easy introduction to the IEEE 1588 technology.
The STM32F207 is a microcontroller by STMicroelectronics that implements IEEE1588 hardware timestamp support in the Ethernet MAC layer. Both time stamping and implementation of an adjustable real-time clock in hardware enables a synchronization accuracy in the nanosecond range.

The following diagram shows the offset from the master values after the synchronization initiation of a long term test.
Fig. 2: Offset from master values in synchronized status
The following diagram shows the offset from master value distribution of the long-term test:

The IXXAT IEEE1588 stack offers a large number of configuration possibilities and completely implements the IEEE1588-2008 standard. The stack has a management API, via which a management device can be implemented. Configuration for a boundary clock or transparent clock with any number of Ethernet interfaces is also possible.
