Tascam CG-2000 Master Clock Generator

Tascam CG-2000

Video sync / master clock generator for broadcasting and post-production

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 CG-2000 is at the top of its class.

Features:

• The CG Series includes  three distinct models tailored to different types of studios.The CG-2000 is designed for the needs of broadcasting and post production, the CG-1800 for small to large-scale video/audio synchronization 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), this unit is key in the creation of high-precision synchronization systems - with word output frequency stability of ±0.005ppm or less per day.

• The CG-2000 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.

• The CG Series has multiple functions to support maintenance, and the identification of issues if problems occur. The analyzer function measures output device termination, input level measurement (for CG-2000 and CG-1800), and the measurement of input frequencies. These built-in features enable the devices 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. The CG Series 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.

• The CG Series is the latest in the line of innovative TASCAM professional digital products – engineered with the latest digital clocking technology.
