AVN-GMC IEEE1588 PTP Grandmaster Clock with GPS Receiver 1

1. AVN-GMC IEEE1588 PTP Grandmaster Clock with GPS Receiver

Introduction

Fig 1-1: The AVN-GMC Front Panel

The AVN-GMCS is a PTPv2 grandmaster clock for use with AoIP

applications. 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.
