Brainstorm Electronics DXD-16 Universal Clock

The DXD series from Brainstorm is designed to ease the transition to IP. The agship model DXD-16 is a PTP Grandmaster clock, GPS capable 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

Barinstorm’s 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.
Four Gigabit Ethernet ports (RJ45) are available on the DXD-16. 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
6 independent sync pulses and clocks are generated simultaneously by the DXD-16 and are routed 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.

DXD as a PTP Slave or PTP Grandmaster

• It has the capability of being a PTP slave or a PTP Grandmaster and gives the operator exceptional flexibility:
• As a stand-alone Master locked to its internal oscillator or GPS, it will provide sync to the network via PTP ports and to the legacy equipment via the The Brainstorm Unique Universal Outputs, simultaneously.
• As a PTP master, the DXD can lock to an external sync source such as 10 MHz sine wave, Word Clock, AES or any standard Video Sync so the IP network locks to the existing sync sources.
• As a PTP slave, it can generate legacy sync to keep the legacy equipment locked to the network.

GNSS / GPS
A GPS receiver can be installed in either unit. GPS not only provides an extremely accurate timing source, it also enables DXD’s in remote locations to be locked and in phase with one another. Additionally, with the GPS option, the DXD will have a higher priority as a PTP Grandmaster.

Auto Fail-over
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.

Power Redundancy
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.

Battery Backup
The internal time-of-day clock is battery backed-up to keep it running while power is off.
