All models use a high-precision OCXO (oven-controlled crystal oscillator) that boasts a clock frequency precision of +/-0.01ppm*1 and a frequency stability of +/-0.005ppm per day. In addition, the CG-2000 is equipped with an external input connector that supports a 10MHz signal, allowing it to be connected to a rubidium clock or GPS clock, when possible, for even higher precision for the system.The jitter management circuit developed by TASCAM reduces external clock jitters, enabling a stable clock signal to video and word outputs.A glitch-free relock circuit maintains a sustained clock phase even during clock dropouts and recovery, thus effectively preventing noise and skipping from occurring, delivering high reliability and stability to users.*1 The numerical value at the time of factory shipment.
The CG-2000 and CG-1800 come equipped with 4 video outputs. All series include 12 word clock outputs, two AES3/11 and two/PDIF digital outputs, enabling the construction of large-scale synchronization systems.Furthermore, they are compatible with 2xFs, 4xFs, and 256xFs outputs, as well as Pro Tools and other DAW systems.The CG series is developed so that the cause of any malfunctions can be investigated during maintenance when problem occurs.The termination of output equipment, measuring of the input level (only for the CG-2000 and the CG-1800), and the analyzer function that measures input frequency are all included, supporting troubleshooting should a problem occurs. The word clock’s output level can be adjusted to different levels, allowing for optimum signal levels to be supplied to connecting equipment. As another function that supports the detection of problems, a logging function is also included.
Since crystal oscillators change over time, regular calibration is necessary in order to keep the oscillator in its best condition.The CG series is equipped with a self-calibration function, enabling users to perform maintenance through easy operations*2. The design takes careful measures to attain durability, including the usage of the nut-coupling Amphenol BNC connectors that are extremely resistant against pulling and twisting, and independent circuit boards for each connector that prevent contact failures caused by twisting.TASCAM’s accumulated experience and know-how in digital synchronization technology through its development of professional equipment has been refined to create products specialized in clock synchronization.The CG series is a lineup of professional-level master clock generators that was the result of an exhaustive injection of TASCAM technology.*2 Use of the self-calibration function requires preparation of a separate PPS-output 10MHz oscillator with a built-in GPS antenna.
With two power supply circuits, the CG-2000 features redundancy to prevent mishaps caused by power outages.
With two inputs each for video reference and world clock signals, there is redundancy to prevent problems due to external clock interruption.
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.
The CG-2000 constantly measures the external reference clock. In devices that do not have built-in countermeasures, and the master clock signal drops out, the video reference and word clock signals could become out of phase, and sound might skip during the dropout - and again during recovery. In the CG-2000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover. During this time, the video reference and word clock signals are kept in-phase, so restoration of synchronization to the reference signal can occur without glitches - preventing video/audio noise and skipping sounds when recovering from a dropout.
The crystal oscillator is the heart of the clock generator, In the CG-2000, 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*, 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.*factory default value.
An external input connector that supports a 10MHz signal enables the CG-2000 to be connected to a rubidium clock or GPS clock for even higher precision.
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.
Analog NTSC/PAL and digital HD Tri-level video signal formats are supported.
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-2000 display, you can also capture the log as a CSV-format file on a USB flash drive. Moreover, you can also monitor the conditions of trouble occurrence by using GPO parallel output.
