IEEE 1588 timing system
4 August 2010
Electronics Technology
Expanding its range of IEEE 1588 synchronisation components, Conemtech has introduced the new M50 module form factor for high accuracy time and frequency synchronisation. The 29 x 29 mm module sold under the name of M50-34 is targeted for time and frequency masters as well as time subscribing devices in telecommunications and smart grid networks.
The launch is made after completing the development of a surface mounted device based on the foundation of previous chip and module developments. This latest module brings the complete subsystem for a synchronised network interface down into a singular device incorporating all the electronic components between the Ethernet transformer and the main processor. It reduces the components count, simplifies the layout and lowers the board manufacturing cost for products requiring external packet-based synchronisation.
This technology enables any device with an Ethernet interface to synchronise to a PTP master clock in the network at 100 ns accuracy by simply rewiring the Ethernet interface. The M50 presents a stable frequency and a precise pulse-per-second and time-of-day to the slave device. The M50-34 can be used as time source backup for a local GPS as it is able to involve a local time source in the selection process of the best clock in the network.
