Introduction
The Model 5401A Dante Leader Clock pro-
vides 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)
compatibility 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 devic-
es. The Model 5401A also generates eight
sine wave audio tones on Dante transmit-
ter (output) channels which can be useful
during audio and data network installation,
maintenance, and operation. A sync input
connection allows the Model 5401A’s in-
ternal 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-pro-
duction studios, commercial and education-
al theater environments, and entertainment
applications. Only power and one, two, or
three Ethernet network connections 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 implementations.
For high-reliability audio applications two
of the interfaces can support Dante redun-
dancy operation while the third is used for
accessing the management webpages. To
meet the latest interoperability standard the
Model 5401A’s Dante implementation sup-
ports AES67-2018. The unit also integrates
with the Dante Domain Manager™ (DDM)
software application.
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 5401A can be powered by 100-
240 V, 50/60 Hz mains or a source of 12
volts DC. Both can be simultaneously con-
nected to provide redundant operation. The
lightweight enclosure mounts in one space
(1U) of a 19-inch equipment rack. Industry-
standard connectors are used for Ethernet,
DC power, and AC mains interconnections.
Updating the Model 5401A’s operating
software can be easily performed using a
standard USB flash drive.
