Brainstorm offers the 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 DXD-8 Universal Clock, a precision multi-format reference generator generates up to four 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.

The DXD-8 generates up to four independent sync pulses and clocks simultaneously and routes them to the eight BNC universal outputs. Universal Outputs give the DXD-8 great flexibility as they can output any of the generated legacy reference signals. Included are 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.

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.
