The Model 5401 Dante Master Clock provides precise timing signals for applications that utilize the Dante® audio-over-Ethernet 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 5401 provides the PTPv1 (IEEE® 1588-2002) compatibility that’s required by Dante. In addition, the unit supports PTPv2 (IEEE 1588-2008) for AES67 applications. A word clock output provides a timing reference for use by external devices. The Model 5401 also generates up to eight sine-wave audio tones on Dante transmit (output) channels, useful during audio network installation, maintenance, and operation. A sync input connection allows the Model 5401’s internal oscillator to synchronize with a variety of timing reference signals.

The Model 5401 is suitable for use in fixed and mobile broadcast facilities, postproduction studios, commercial and educational theater environments, and entertainment applications. Only power and one or two Ethernet network connections are required for full operation. Using Dante’s inherent capabilities two Model 5401 units can serve in primary and secondary master clock roles for redundant operation
