The VDA-SDI is a 1 input, 8 output distribution amplifier specifically designed for serial digital
SDI (4:2:2 component) video signals. The signal present at the input will be reproduced at each of
the 8 outputs.
The reclocking input circuitary provides reduced jitter at the outputs. Input and output cable
lengths may be up to 300 meters.
Input and output connectors are the BNC type.
