The Model 5402 Dante Leader Clock with GNSS Synchronization provides precise timing signals for applications that utilize the Dante audio-over-IP (AoIP) media networking technology. The unit implements a high-performance IEEE® 1588 precision time protocol (PTP) server, compatible with the requirements of Dante and capable of simultaneously supporting the timing needs of up to hundreds of Dante-compatible devices. As expected, the Model 5402 provides the PTP v1 (IEEE 1588-2002) compatibility that's required by Dante. In addition, the unit supports PTP v2 (IEEE 1588-2008) for AES67 applications. The unit includes an integrated GNSS (satellite) receiver to allow a precise timing reference to be acquired from the four major constellations: GPS, Galileo, BeiDou, and GLONASS. In addition, a sync input connection allows the Model 5402's internal oscillator to be synchronized with a variety of external timing and reference signals. A word clock output provides a general-purpose timing reference for use by external devices.
To meet the latest interoperability standard the Model 5402's implementation supports AES67-2018. The unit also integrates with the Dante Domain Manager™ (DDM) software application. With DDM, support for ST 2110 and AES67 can take place alongside Dante audio. And with multiple Model 5402 units all utilizing GNSS-based timing, studios across town or even around the globe can share audio.
The Model 5402 also generates eight sine-wave audio tones on Dante transmitter (output) channels which can be useful during audio network installation, maintenance, and operation.
The Model 5402 is suitable for use in fixed and mobile broadcast facilities, post-production studios, commercial and educational theater environments, and entertainment applications. Only power, GNSS antenna, and one, two, or three Ethernet network connections are required for full operation. Using Dante's inherent capabilities two Model 5402 units can serve in primary and secondary Leader clock roles for redundant operation.
The unit's three Gigabit Ethernet ("GigE") network interfaces can be configured for use in a range of network implementations. For high-performance applications two of the interfaces can support redundant Dante operation while the third can be used for accessing the management webpages.
An integrated web server allows fast and flexible monitoring and configuration of the unit's networking, clocking, and Dante performance. Front-panel indicators, an LCD display, and pushbutton switches provide users with direct access to key operating parameters.
The Model 5402 can be powered by 100-240 V, 50/60 Hz mains or a source of 12 volts DC. Both can be simultaneously connected to provide redundant operation. The lightweight enclosure mounts in one space (1U) of a standard 19-inch rack. Industry-standard connectors are used for Ethernet, GNSS antenna, DC power, and AC mains interconnections. Updating the Model 5402's operating software can be easily performed using a USB flash drive.
Applications
Applications for the Model 5402 include broadcast and post-production facilities, college and university audio networks, arenas, stadiums, and corporate installations — virtually any application where substantial numbers of Dante-compatible devices are utilized. The Model 5402 will serve as a stable and consistent Leader clock for the entire Dante "network." And, as expected, the Model 5402 is compatible with all Dante devices, no matter what their primary function or manufacturer. Applications that utilize devices compatible with AES67 will also benefit from the Model 5402's resources. With its ability to "lock" to satellite-based time standards, multiple Model 5402 units can be deployed literally "around the world" and maintain synchronized PTP performance.
