Tascam CG-2000
The best in the CG series for broadcasting stations and post-production sites
With redundancy of both the power supply and the video/audio clock, as well as many other functions, the CG-2000 meets the strict demands of broadcasting and post production.
External clock jitter is reduced using an original TASCAM circuit design that incorporates a high-performance video clock generator device, featuring an FPGA (Field Programmable Gate Array) and a PLL (phase-locked loop) circuit with a discrete filter. This enables a stable clock signal to be provided to the video/word outputs, improving system stability.
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.
