Tascam CG-2000 Master Clock Generator

The CG-2000 is designed for the needs of broadcasting and post production. The crystal oscillator is the heart of the clock generator. In 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 ppm1, 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 FPGA2 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.




  • Stable synchronization between picture and sound
  • Flexible system setup with a large variety of audio and video formats (Audio: Wordclock, AUS3, AES11, SPDIF, Video: NTSC, PAL, HD tri-level)
  • High-quality OCXO (Oven Controlled Crystal Oscillator) oscillator for highly accurate clock signal generation
  • Jitter management circuit and glitch-less relock management to avoid problems caused by master clock signal
  • Clock input supports clock rates up to 10 MHz
  • 4 video sync outputs, 12 wordclock outputs, 2 AES3 or AES11 outputs, 2 SPDIF outputs
  • 2 wordclock outputs support Fs/4, Fs/2, 2 Fs, 4 Fs and 256 Fs to be used with ProTools and other DAW software
  • Support for 0.1%, 4 % pull-up/pull-down
  • Self-calibration function* allows maintenance by operator for optimum accuracy at any time
  • Output levels of the wordclock connectors can be adjusted
  • Analyzer feature allows to measure input frequencies, input levels and the termination of output devices
  • Logging function for troubleshooting (check the log on the display or capture a CSV-format file on a USB flash drive)
  • Up to 4 system settings can be saved for recall and saved settings can be imported and exported via USB
  • Panel-lock to prevent misoperation
  • Organic EL display with a wide viewing angle
  • Firmware updates possible using the USB port
  • Highest reliability through redundant power supply and redundant video sync and wordclock inputs
  • GPO signaling outputs for monitoring the error status
