Tascam CG-2000 Video Sync/Master Clock Generator

Tascam CG-2000 Video Sync/Master Clock Generator

Tascam CG-2000 Video Sync/Master Clock Generator Details

Tascam CG-2000 Video Sync/Master Clock Generator is the latest in the line of innovative TASCAM professional digital products ?" engineered with the latest digital clocking technology. With redundancy of both the power supply and the video/audio clock, as well as many other functions that meet the strict demands of broadcasting and post production, the Tascam CG-2000 Video Sync/Master Clock Generator is at the top of its class. It is designed for the needs of broadcasting and post production. The crystal oscillator is the heart of the Tascam CG-2000 Video Sync/Master Clock Generator. 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), this unit is key in the creation of high-precision synchronization systems - with word output frequency stability of ±0.005ppm or less per day.


Tascam CG-2000 Video Sync/Master Clock Generator is equipped with an external input connector that supports a 10MHz signal. This allows it to be connected to a rubidium clock or GPS clock for even higher precision. External clock jitter is reduced using an original TASCAM circuit design that incorporates a high-performance video clock generator engineered with a FPGA*2 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. The glitch-free relock circuit prevents noise and skipping sounds caused by master clock dropouts. In addition to (12) word clock outputs and (4) video outputs, the digital outputs include (2) AES3/AES11 and (2) S/PDIF outputs, making this unit useful for large-scale audio/video synchronization systems, and a wide variety of other applications. Of the (12) word outputs, two also support x2Fs, x4Fs and 256Fs output - enabling them to be used in systems with ProTools and other DAW software.


Tascam CG-2000 Video Sync/Master Clock Generator has multiple functions to support maintenance, and the identification of issues if problems occur. The analyzer function measures output device termination and the measurement of input frequencies. These built-in features enable the device to provide troubleshooting support. Additionally, a logging function enables issues to be listed, and saved to a CSV file format on a USB flash drive.


Since crystal oscillators change over time, regular calibration is necessary. In order to avoid possible sync problems, timely inspections ?" along with regular maintenance is required. Tascam CG-2000 Video Sync/Master Clock Generator has a self-correction function, enabling users to conduct maintenance using an external signal input*3 and simple operations. Amphenol BNC connectors on the chassis use nuts for coupling ?" making them very durable, Also, a single circuit board is used for each connector - providing excellent resistance to the twisting and pulling of cables, and the suppression of interference between connectors.
