Tascam Video Sync/Master Clock Generator

The CG-2000 from Tascam is specifically designed for the needs of broadcasting and post production. An OCXO (oven-controlled crystal oscillator) is used for its high precision and because it’s not affected by the temperature of the environment. with a clock frequency precision of 0.01 ppm the unit delivers high-precision synchronisation with a frequency stability of +/-0.005 ppm or less per day.

The unit is equipped with an external input connector that supports a 10MHz signal that allows it to be connected to a rubidium clock or GPS clock for even higher precision. External clock jitter is reduced using an original circuit design that incorporates a high-performance video clock generator engineered with a FPGA 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.
