1 – Introduction
Thank you very much for purchasing a TASCAM CG-1800/
CG-1000 Master Clock Generator.
Before using this unit, please read this manual thoroughly to
ensure you understand how to operate it correctly. We hope
that you will enjoy using this unit for many years.
After you have finished reading this Owner’s Manual, please
keep it in a convenient place for future reference. You can also
download a copy of this manual from the TEAC Global Site

Features
• Internal oscillation element uses a high-precision OCXO
(oven-controlled crystal oscillator), which is not affected by
environmental temperature
• Creating systems with even higher precision is possible
using an external input connector that supports 10MHz
• Jitter management circuit provide stable clock
• Glitch-free relocking circuit prevents noise and skipping
during clock dropouts and recovery
• Numerous output connectors, including 12 word clock
outputs, enable use even in large-scale video/audio
synchronization systems
• Supports input and output of a variety of video signal
formats, including NTSC, PAL and HD tri-level (CG-1800
only)
• AES3 and AES11 signals can also be used for external
master clock input sources
• Analyze function can measure output device termination
(CG-1800 only)
• Word clock output level adjustment function allows signals
to be provided to other devices at optimal levels
• Self-calibration function using an external oscillator
(atomic/GPS 10MHz, GPS PPS)*
• Word clock up to 192 kHz supported
• Supports 0.1% PULL UP/DOWN between 24F (Film) and
29.97F (NTSC) and 4% PULL UP/DOWN between 24F (Film)
and 25F (PAL) (CG-1800 only)
• Up to 4 system settings can be saved to buttons for recall,
and saved settings can be imported and exported via USB
• Tough nut-coupling BNC connectors made by Amphenol
• Construction uses independent circuit boards for each
connector to prevent contact failures due to twisting
• Three-prong inlet type power cable included
• Panel-lock switch to prevent misoperation
• 128x64-pixel organic EL display with a wide viewing angle
• Aluminum front panel that matches other studio
equipment
• Firmware updates possible using the USB port
• EIA 1U rackmount size
• RoHS-compliant
*Use of the self-calibration function requires preparation of
a separate PPS-output 10MHz oscillator with a built-in GPS
antenna.
