Tascam CG-1800 Video Sync and Master Clock Generator

Tascam CG-1800 Video/Audio Synchronization System

The Tascam CG-1800 is precisely engineered for small to large-scale video and audio synchronization systems. Utilizing an OCXO (oven-controlled crystal oscillator), the CG-1800 achieves remarkable precision and is immune to environmental temperature variations. The unit boasts a clock frequency precision of 0.01 ppm and delivers stable synchronization with a frequency stability of +/-0.005 ppm per day.

An innovative circuit design, incorporating a high-performance video clock generator with FPGA and a PLL circuit, effectively reduces external clock jitter. This ensures a stable clock signal for the video and word outputs, thereby enhancing overall system stability.
