Product Overview
DXD-8 Universal Clock
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 precision multiformat reference generator generates up to 4 independent video syncs and audio clocks simultaneously. With the PTP option, the DXD-8 acts as a clocking bridge between an IP infrastructure and legacy A/V equipment.
Flexibility and easy integration
- 4 separate Reference Generators
- 8 BNC outputs: WC, AES, VID SYNC or 10MHz (user-defined)
- 2 BNC inputs for external references with failover
- NTP Server & NTP Client
- PTP Grandmaster or PTP Slave (w/ PTP option)
- GPS Receiver (hardware option)
- Synchronizes to a legacy reference, a PTP network or GPS
- Generates TOD Time Code (w/ DXD/LTC option)
- Remote control via web browser
- Available options: PTP (v2, v1, AVB) , LTC, GPS, OCXO
Customize Your Unit with User-Assignable BNC Outputs
The DXD-8 generates up to 4 independent sync signals simultaneously and routes them to the 8 BNC outputs. These outputs can be set for any of the generated references, video or audio, giving the DXD-8 great flexibility. This includes: all standard SD and HD video sync formats (Black Burst and HD tri-level sync), word clock and AES11 DARS (standard rates up to 384 KHz and all the necessary pull-up/down, including 24:25 conversions, even VSO) and 10MHz. With the Time Code option, LTC is also included.
The DXD-8 can be a PTP slave or a PTP Grandmaster giving the operator exceptional flexibility:
- As a PTP slave, it can generate legacy sync so that the legacy equipment locks to the network;
- As a PTP master, it can lock to an external legacy sync source so that the network locks to the legacy equipment;
- As a stand-alone master, locked to its internal oscillator or GPS, it provides sync to the network via the PTP port and to the legacy equipment via the BNC outputs, simultaneously.
GNSS / GPS
A GPS receiver can be installed in the DXD-8. 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.
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 generated locked to any reference such as 59.97 from 25FPS for example.
Resilience and 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.
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.
IEEE 1588 Network Sync
The optional PTP firmware supports PTP V2, PTP V1 (Dante) and gPTP (AVB). The DXD- 8 can be a PTP Grandmaster or a PTP Slave. Precision Time Protocol (PTP) has been broadly adopted as the network synchronizing standard, which means that the DXD-8 can work in a number of systems. Several PTP profiles are included: AES67, SMPTE 2059 and gPTP.
