Key Features

Overview

The Model 5402 Dante Leader Clock with GNSS Synchro-

nization 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 support

ing 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 Man-

ager™ (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.

As an additional resource, the Model 5402 generates eight

sine wave audio tones on Dante transmitter (output) channels.

These can be useful during audio and data 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 applica-

tions. 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.

For general-purpose use the Model 5402’s GNSS receiver will also report, by way of the front-panel display and/or the management webpages, the current date and time of day, as well as longitude and latitude parameters. In addition, the number of satellites currently “fixed” (locked) and the receiver input power can also be observed.
