The Model 5401A Dante Leader Clock provides precise timing signals for applications that utilize the Dante® audio-over-IP 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 5401A 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. A word clock output provides a general-purpose timing reference for use by external devices. The Model 5401A also generates eight sine-wave audio tones on Dante transmitter (output) channels which can be useful during audio network installation, maintenance, and operation. A sync input connection allows the Model 5401A’s internal oscillator to be synchronized with a variety of timing and reference signals.
