The CG-2000 constantly measures the external reference clock. In devices that do not have built-in countermeasures, and the master clock signal drops out, the video reference and word clock signals could become out of phase, and sound might skip during the dropout – and again during recovery. In the CG-2000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover.

During this time, the video reference and word clock signals are kept in-phase, so restoration of synchronization to the reference signal can occur without glitches – preventing video/audio noise and skipping sounds when recovering from a dropout.
