A Precision Reference Generator with 8 Universal Outputs and a PTP option

The DXD series from Brainstorm is designed to ease the transition to IP.

The DXD-8 Universal Clock, a precision multi-format reference generator generates up to 4 independent video syncs and audio clocks simultaneously. With the PTP option, it acts as a bridge between an IP infrastructure and legacy A/V equipment.

REFERENCEGENERATORWITHUNIVERSALOUTPUTS

The DXD-8 generates up to 4 independent sync pulses and clocks simultaneously and routes them to the 8 BNC universal outputs.

UniversalOutputs offer great exibility compared to dedicated outputs as they can be congured 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.

A high-accuracy internal crystal oscillator (TCXO) provides a very

stable frequency reference (+/- 1ppm). External legacy signals can also

be used as reference: Word Clock, AES, Video Sync (SD & HD) and

10MHz. The generated signals 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.

complies with IEEE 1588 PTP V2 and can be either a PTP master or

slave Clock. PTP (Precision Time Protocol), dened in IEEE 1588, has

been broadly adopted by manufacturers as a network synchronizing standard, which means that the DXD-8 can work in a number of systems.

PTP proles supported by the DXD-8 include AES67 and SMPTE 2059.

As a PTP slave, the DXD-8 synchronizes its internal clocks to the PTP Grandmaster while generating the different sync pulses and clocks. Alter-

natively it can itself fulll the function of Grandmaster either locked to the

GPS signal (option) or to it’s internal oscillator.

The DXD-8 has one Gigabit Ethernet port (RJ45).

GNSS/GPS

A GNSS/GPS receiver can be installed as an option in the DXD-8 and provide the highly accurate and stable GPS clock as a timing source. Multiple DXD’s in remote locations will be locked to each other and in phase once they are GPS referenced.

RESILIENCE&REDUNDANCY

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-8 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.

Two external 12VDC power supply can be connected to the DXD-8. It

can operate with either of these power sources and they can both act as a back-up for the other with auto switch-over in the event of a failure.

REMOTECONTROL

All functions and settings can be monitored and altered via a web browser.

OPTIONS

• PTP (software): With the PTP option installed, the DXD-8 can be a PTP

master or slave.

• OCXO (hardware): An oven-controlled-oscillator (OCXO) is available

providing greater long-term time and TOD accuracy (+/-10ppb, which is less than +/-10 frames per year). The greater accuracy is also useful in

GPS systems where extended GPS dropouts may be expected.
