3.12.1 SDI Inputs
3.12.2 SDI Outputs
3.12.3 Reference Input
Operation to full specification is only possible with a correctly terminated, noise-free, stable,
black sync reference input. While lock may be achieved with an unsuitable sync source, the
increased jitter evident on the SDI output will affect locking and cable length performance at
the receiving equipment.
Serial digital inputs to the module are made
via two BNC connectors which terminate in
75 Ohms.
Serial digital outputs from the module are
made via four BNC connectors which
terminate in 75 Ohms.
An external sync input to the module is made
via passive loop-through BNC connectors
which terminate in 75 Ohms.
Note:
If the loop-through facility is not used, the unused BNC socket must be fitted with a 75 Ohm
terminator.
