    10 bit synchroniser allowing the serial digital output to be timed to an analogue reference. The DEC105S also has a serial digital (SDI) input. This allows it to be used as a synchroniser, with some additional control over gains and timing.

  • Page 5: Operating Modes

    Crystal Vision Introduction Operating modes To provide optimum performance with a wide range of sources the DEC105S can operate in a number of different modes. Input modes Description Uses a line-based comb decoder, which mixes to simple decoder 10 bit comb PAL/NTSC composite when the comb would produce artefacts.
