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.
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.

Manual & Data Sheet
How many different sync signals can the DXD-16 generate simultaneously?
The DXD-16 can generate up to 6 different sync signals similtaneously in any combination of WC, AES, Video Sync or 10MHz. These sync signals are then sent to the 16 universal outputs.
Can the DXD-16 be set up to have 16 video sync outputs, 1080p tri-level sync for example?
Yes, the Universal Outputs can be set to any of the formats mentioned in FAQ #1 above, which means that, if 16 outputs of 1080p tri-level sync is what is needed, the DXD-16 can be set up to do just that.
Are the 4 DXD-16 Ethernet ports identical?
Each network connector supports an electrically and logically independent network. From a PTP standpoint, the 4 ports are identical but firmware updates and remote control are from port #4 only.
