NOTES:
1. Video outputs are genlock to the internal clock with Composite analog video at SCH phase 0.
2. Video outputs are genlock to the REF Composite video input. Loss of the REF signal will cause the
outputs to free run.
3. Video outputs are always genlock to the selected video input, if a signal is present. Loss of input signal
will caused the outputs to genlock to the internal clock.
4. All video outputs’ timing locks to the SDI input while the phase of the Composite analog output is lock to
the REF input.
5. REF IN (Black Burst or Color Black signal). The REF IN mode is only active with the SDI input or Input
None selected. It provides the phase lock timing for the Composite analog output while the other timing is
derived from the incoming SDI video. The REF IN Black Burst signal must sync and frame locked to the
SDI 601 input.
