Sonifex has released the AVN-GMC PTPv2 Grandmaster Clock, the company’s first product for use in Ravenna networks since it joined the Ravenna (audio over IP) group.
IEEE 1588 PTP (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-GMC is designed to perform this role simply and accurately, acting as a GPS receiver and enabling sub micro second synchronisation between all nodes.
In normal operation, the unit has PTPv2 time stamping resolution to 8ns. The AVN-GMC combines a GPS receiver, a PLL (phase lock loop) and a specialist on-board clock device to create the precise, low jitter clock signals required to drive the physical transceiver’s time stamping circuitry, also providing holdover if the GPS signal is lost.
