The DVJ-3000 is designed to reduce the jitter in
270 Mb/s SDI or ASI signals.
Due to the fact that true loop through inputs are not
normally available in most digital equipment, the
signal is frequently subject to automatic equalisation
and reclocking.
Together with noise pickup this leads to an inevitable
increase in jitter in the signal.
The only successful way to overcome this is to
regenerate the signal with a new clock signal
referenced to the long-term data rate.
The DVJ-3000 provides this solution with a Voltage
Controlled Crystal Oscillator (VCXO) operating in
conjunction with a First In First Out (FIFO) memory
to provide a constant output data rate, which removes
any short-term data rate errors. |
Up to twelve DVJ-3000’s or other Eurocard modules may be housed in one 3 RU frame.
The DVJ-3000 supports redundant power supply
inputs.
For input jitter within this mask,
output jitter < 0.125 UI. |
