CG-2000 Master Clock Generator

The CG Series master clock generators are based on a high-precision crystal oscillator with jitter management and glitch-free relocking for ultra-high clock precision. The CG-2000 is designed for the needs of broadcasting and post production, the CG-1800 for small to large-scale video/audio synchronisation systems, and the CG-1000 for recording studios, live sound applications and professional musicians.

The crystal oscillator is the heart of the clock generator. In each model of the CG Series, an OCXO (oven-controlled crystal oscillator) is used for its high precision, and the fact it is not influenced by the temperature of the environment. Boasting a clock frequency precision of 0.01 ppm*1, which exceeds that of a TCXO (temperature-compensated crystal oscillator), these units are key in the creation of high-precision synchronization systems with word output frequency stability of ±0.005 ppm or less per day. Each model is equipped with an input connector that supports a 10-MHz signal. This allows it to be connected to a rubidium clock or GPS clock for even higher precision.
