Master Clock Generator

CG-1000

An OCXO for the best clock precision available

The CG-1000 is a master clock generator based on a high-precision OCXO – Oven Controlled Crystal Oscillator – with jitter management and glitch-free relocking for the best clock precision available, ideal for recording studios, sound engineers and musicians

Features at a glance

  • 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
  • AES3 and AES11 signals can also be used for external master clock input sources
  • Analyzer function that can measure input frequencies
  • Optimal levels can be provided to other devices by adjusting wordclock output levels
  • Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS)
    *Use of the self-calibration function requires the use of a separate PPS-output 10MHz oscillator with a built-in GPS antenna
  • Word clock performance up to 192 kHz
  • Up to (4) system settings can be saved to buttons for recall, and saved settings can be imported and exported via USB
  • Durable nut-coupling BNC connectors made by Amphenol
  • Independent circuit boards for each connector prevents contact failures due to twisting
  • Three-prong IEC power cable included
  • Panel-lock switch can be used to prevent inadvertent changes to unit operation
  • 128x64-pixel organic EL display with a wide viewing angle
  • Firmware updates possible using the USB port
  • EIA 1U rack mount size
  • RoHS-compliant product
