AVN-GMCS IEEE1588 PTP Grandmaster Clock with GPS Receiver
The AVN-GMCS is a PTP GPS receiver and grandmaster clock used for synchronising AoIP audio networks, such as those used by RAVENNA and AES67. IEEE1588-2008 PTPv2 (precision time protocol) is used to synchronise all the nodes within a network. To achieve this one of the nodes must become the master clock and distribute time packets to the others. The AVN-GMCS is designed to perform this role simply and accurately, enabling sub micro second synchronisation between all nodes.
Trials have been performed by other manufacturers using the unit to sync their AoIP networks to ensure compatibility and now that these have been successful, the product has been released. Some new features that have been added into the latest hardware include:
