Highlights

  • Internal clock uses a high-precision OCXO (oven-controlled crystal oscillator) that is not influenced by the temperature of the environment
  • External input connector that supports 10MHz, allowing creation of systems with even higher precision
  • Jitter management circuit provides stable clock
  • Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
  • Numerous output connectors, including (12) word clock outputs, enabling the use in large-scale audio synchronization systems

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. 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. 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.
