    M5402 - Overview

    The Studio Tech 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 IEEEr 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 PTPv1 (IEEE 1588-2002) compatibility that's required by Dante. In addition, the unit supports PTPv2 (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 additional, 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.

    The Model 5402 integrates with the Dante Domain ManagerT (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 is suitable for use in fixed and mobile broadcast facilities, post-production studios, commercial and educational theater environments, and entertainment applications. Only power, a 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 backup Leader clock roles for redundant operation.

    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 19-inch equipment 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.

    Please Note! Studio Technologies offers both the Model 5401A Dante Leader Clock and the Model 5402 Dante Leader Clock with GNSS Synchronization. They are intended for essentially the same applications - to serve as a Leader Clock for Dante digital audio applications. Everything that can be done with the Model 5401A can be done by the Model 5402. But the latter includes an integrated satellite receiver which is capable of deriving a precise time signal from the major GNSS (Global Navigation Satellite System) constellations. The Model 5402 supports these constellations: GPS (US), Galileo (Europe), BeiDou (China), and GLONASS (Russia). In addition, the QZSS augmentation system from Japan can be enabled (it can add precision to GPS for certain locations in Asia).
