Tascam CG-2000 MASTER CLOCK GENERATOR

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

The unit comes equipped along with an external input connector that is capable of supporting a 10MHz signal that is allowing it to be connected to a rubidium clock or GPS clock for even higher precision. External clock jitter is being reduced with the use of an original circuit design that incorporating a high-performance video clock generator engineered along with a FPGA and a PLL (phase-locked loop) circuit that comes with a discrete filter. This is enabling a stable clock signal to be provided to the video/word outputs, which is totally improved the system stability.

In addition to twelve Wordclock outputs and four video outputs, the digital outputs come including a two AES3/AES11 and two S/PDIF outputs, this makes this unit useful for large-scale audio/video synchronization systems and a wide variety of other applications. Of the twelve Wordclock outputs, two also come supporting x2 Fs, x4 Fs and 256 Fs output, this enables them to be used in systems with Pro Tools and other DAW software.

The unit comes featuring a multiple functions for supporting the maintenance and the identification of issues if problems occur, this allows the device to be able to provide troubleshooting support. Additionally, a logging function is enabling the issues to be listed, and saved to a CSV file format on a USB flash drive. A self-correction function is allowing the users for conducting the maintenance with the use of an external signal input and simple operations.

The GC-2000 is designed for providing the redundancy for the power supply and the video/audio clock, as well as alarm outputs in the event an error occurs. Amphenol BNC connectors on the chassis use nuts for coupling for extra durability, that comes along with a single circuit board used for each connector. This is providing a good resistance to the twisting and pulling of cables, and the suppression of interference between connectors.
