192kHz Video Sync/Master Clock Generator with Oven-controlled Crystal Oscillator, Jitter Management, 12 Word Clock Outputs, 4 Video Outputs, and Self-correction Function |
TThe 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.

Designed for High Reliability and Dependable Stability |
External clock jitter is reduced using an original TASCAM circuit design that incorporates a high-performance video clock generator device, featuring an FPGA (Field Programmable Gate Array) 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. |
Multiple Functions Support Maintenance and Identification of Issues If Problems Occur |
One function that enables identification of the causes of trouble is the logging function. In addition to being able to check the log on the CG-1800 display, you can also capture the log as a CSV-format file on a USB flash drive. |
Designed for Durability |
Since the Amphenol BNC connectors use nuts for coupling, they are extremely resistant to pulling, twisting and multiple connect-disconnect cycles. |
The construction uses a single circuit board for each connector. This provides excellent resistance to the twisting and pulling of cables and suppresses interference between connectors. |
