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. RAVENNA (of which AES67 is a subset) allows for the distribution of audio across a network. For this to be possible, each of the nodes needs to be time synchronised with one another. RAVENNA uses PTP time stamping to achieve this, which distributes the network time but also works out the latency involved in the delivery and adjusts the time at each node accordingly. Unit configuration is achieved easily either with the front panel controls or the webserver, including the setup of the PTP profiles. The AVN-GMCS supports the Default (RAVENNA), Media (AES67) and AES-R16-2016 (SMPTE-ST 2059-2 \u0026amp; AES67 compatible) profiles and has a ‘Custom’ profile page for you to define your own. In normal operation, the unit has PTPv2 time stamping resolution to 8nsec. It uses a combination of 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, and provide holdover if the GPS signal is lost. The specialist on board clock is available in two different types: TCXO \u0026amp; OXCO, which vary in both and accuracy\u003c\/p\u003e\u003ch3\u003eProduct Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eAES67\/RAVENNA\/AES-R16 compatible.\u003c\/li\u003e\n\u003cli\u003eGPS satellites received indicator.\u003c\/li\u003e\n\u003cli\u003eMaster and slave sync modes.\u003c\/li\u003e\n\u003cli\u003e8ns PTPv2 time stamping resolution.\u003c\/li\u003e\n\u003cli\u003eHoldover drift \u0026lt;1ppm, with an option for \u0026lt;0.01ppm.\u003c\/li\u003e\n\u003cli\u003eAES-3id, wordclock \u0026amp;
