DANTE LEADER CLOCK WITH GNSS SYNCHRONIZATION
Introduction
The Model 5402 Dante Leader Clock with GNSS Syn-
chronization provides precise timing signals for applica-
tions that utilize the Dante audio-over-IP (AoIP) media
networking technology. The unit implements a high-per-
formance 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 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) chan-
nels. 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
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 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 redundant Dante operation while
the third can be used for accessing the management
webpages.
An integrated web server allows fast and flexible monitoring
and configuration of the unit’s networking, clocking, and
Dante performance. Front-panel LED indicators, an LCD
display, and pushbutton switches provide users with direct
access to key operating parameters.
The Model 5402 can be powered by 100-240 V, 50/60 Hz
mains or a source of 12 volts DC. Both can be simultane-
ously connected to provide redundant operation. The light-
weight 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 inter-
connections. Updating the Model 5402’s operating software
can be easily performed using a USB flash drive.
Applications
Applications for the Model 5402 include broadcast and
post-production facilities, college and university audio
networks, arenas, stadiums, corporate installations, and
virtually any application where substantial numbers of
Dante-compatible devices are utilized. The Model 5402
will serve as a stable and consistent Leader clock for the
entire Dante “network.” And, as expected, the Model 5402
is compatible with all Dante devices, no matter what their
function or whom their manufacturer. Applications that uti-
lize devices compatible with AES67 will also benefit from
the Model 5402’s resources. With its ability to “lock” to a
satellite-based time standard, multiple Model 5402 units
can be deployed literally “around the world” and maintain
synchronized PTP performance.
Why a Dedicated Dante Leader Clock?
With Dante ubiquitous in fixed and mobile facilities of all
sizes and types, the need arose for a cost-effective, pur-
pose-designed, dedicated Leader clock. While an inherent
