The DXD series from Brainstorm is designed to ease
the transition to IP. The DXD-16 Universal Clock is a PTP Grandmaster
clock with GPS receiver and a multi-format legacy reference generator.
While working in a PTP environment, the DXD-16 keeps legacy equipment
perfectly synchronized with the IP infrastructure, or vice-versa.
IEEE 1588 network sync.
The DXD-16 can be either a PTP Grandmaster, slave
or Boundary Clock. PTP (Precision Time Protocol), defined in IEEE 1588,
has been broadly adopted by manufacturers as a network synchronizing
standard, which means that the DXD-16 can work in a number of systems.
PTP profiles supported by the DXD-16 include AES67 and SMPTE 2059.
As a Boundary Clock, the DXD-16 can be a slave to a
Grandmaster on one of its attached networks, synchronize its internal
clocks to that Grandmaster, and distribute the same Grandmaster time in
its role as PTP master to the remaining attached networks. Alternatively
it can itself fulfill the function of Grandmaster and be PTP master on
all attached networks.
The DXD-16 has four Gigabit Ethernet ports (RJ45).
The different ports can be used independently or as primary and
secondary pairs. Each network connector supports an electrically and
logically independent network, with the DXD-16 acting as a PTP timing
bridge. The DXD-16 is not a network switch, and for security reasons no
information flows from any network port to any other.
Customize your units with universal outputs.
The DXD-16 generates 6 independent sync pulses and
clocks simultaneously and routes them to the 16 BNC universal outputs.
Universal Outputs offer great flexibility compared to dedicated outputs
as they can be configured for any of the generated legacy reference
signals. This includes all standard SD and HD video sync formats (Black
Burst and HD tri-level sync), word clock and AES-3id (at rates from 32
to 384 KHz, plus all the necessary pull-up/down, including 24:25
conversions, even VSO) and 10MHz.
Accurate and versatile clock generator.
A high-accuracy internal crystal oscillator (TCXO)
provides a very stable frequency reference (+/- 1ppm). An optional
oven-controlled oscillator (OCXO) can be installed. External legacy
signals can also be used as reference, such as Word Clock, AES, Video
Sync (SD & HD) or a 10MHz tone. The generated outputs have extremely
low jitter. The output rates are independent from the reference rate
which means that any rate can be extracted from any reference such as
59.97 from 25FPS for example.
GNSS / GPS.
An external GNSS/GPS receiver can be connected to
the DXD-16 and provide the highly accurate and stable GPS clock and Time
Of Day (TOD) as an external timing source. With this function multiple
DXD-16’s in remote locations will be locked to each other and in phase
once they are GPS referenced. Optionally, an internal GPS receiver can
When using an external reference, a second source
can be connected as fallback in case of failure. If the external
reference becomes unusable, the DXD-16 continues generating, locked
either to the alternate source or to the internal oscillator and
re-locks to the reference when it reappears. These transitions occur
smoothly and gradually with no sync shock to the system.
The internal time-of-day clock is battery backed-up to keep it running while power is off.
An internal 100-240 VAC power supply is provided
as is a DC input for an external 12VDC source. The unit can operate with
either of these power sources and either can act as a back-up for the
other with auto switch-over in the event of a failure.
