Key Features

Overview

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 PTPv1 (IEEE 1588-2002) compat-

ibility that’s required by Dante. In addition, the unit supports

PTPv2 (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 and data 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.

The Model 5401A is suitable for use in fixed and mobile

broadcast facilities, post-production studios, commercial and

educational theater environments, and entertainment applica

tions. Only power and one, two, or three Ethernet network con

nections are required for full operation. Using Dante’s inherent

capabilities two Model 5401A units can serve in primary and

backup 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 implemen

tations. For high-reliability audio applications two of the

interfaces can support Dante redundancy operation while the

third is used for accessing the management webpages. To

meet the latest interoperability standard the Model 5401A’s

Dante implementation supports AES67-2018. The unit also

integrates with the Dante Domain Manager™ (DDM) software

application.
