Master clock generator and video sync for broadcast and post-production.

The TASCAM CG-2000 video sync/master clock generator is 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 these applications. The CG-2000 employs a high-precision OCXO (oven-controlled crystal oscillator) that boasts a clock frequency precision of ±0.01ppm and a frequency stability of ±0.005ppm per day. In addition, the CG-2000 is equipped with an external input connector that supports a 10MHz signal, allowing it to be connected to a rubidium clock or GPS clock for even higher precision for the system. The jitter management circuit developed by TASCAM reduces external clock jitters, enabling a stable clock signal to video and word outputs, while a glitch-free relock circuit maintains a sustained clock phase even during clock dropouts and recovery, thus effectively preventing noise and skipping from occurring, delivering high reliability and stability to users. The CG-2000 comes equipped with four video outputs along with 12 word clock outputs, two AES3/11 and two/PDIF digital outputs, enabling the construction of large-scale synchronization systems. Furthermore, it's compatible with 2×Fs, 4×Fs, and 256×Fs outputs, as well as Pro Tools and other DAW systems. The word clock’s output level can be adjusted to different levels, allowing for optimum signal levels to be supplied to connecting equipment.
