The internal clock employs the high-precision OCXO that is not impacted by environment temperature
The CG-1000 employs 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. 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.

Easily check conditions if problems occur through logging and GPO parallel output
The CG-1000 also equips 12 word clock outputs, two AES3/11 and two S/PDIF digital outputs, enabling the construction of large-scale synchronization systems. Furthermore, it is compatible with 2×Fs, 4×Fs, and 256×Fs outputs, as well as Pro Tools and other DAW systems.
The CG-1000 is developed so that the cause of any malfunctions can be investigated during maintenance when problem occurs. The analyzer function that measures input frequency are all included, supporting troubleshooting should a problem occurs, while 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.
User maintenance enabled by the self-calibration functions via external oscillators
Since crystal oscillators change over time, regular calibration is necessary in order to keep the oscillator in its best condition. The CG-1000 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-1000 is a lineup of professional-level master clock generators that was the result of an exhaustive injection of TASCAM technology.

High-precision synchronization systems can be created
Internal clock uses a high-precision OCXO that 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.
Input connector that supports 10MHz signal – allowing the creation of systems with even higher precision
Abundant Input and Output Connectors Support Use in Large-scale Audio Synchronization Systems
Numerous output connectors, including 12 word clock outputs
Of the 12 word outputs, two also support ×2Fs, ×4Fs and ×256Fs output – enabling them to be used in systems with ProTools and other DAW software.
Designed for High Reliability and Dependable Stability
Jitter management circuit provides stable clock
This enables a stable clock signal to be provided to the word outputs, improving system stability.
Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
In the CG-1000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover.
So, restoration of synchronization to the reference signal can occur without glitches - preventing audio noise and skipping sounds when recovering from a dropout.
Multiple Functions Support Maintenance and Identification of Issues If Problems Occur
Analyzer function that can measure input frequencies
The CG-1000 has an analyzer function that allows it to measure input frequencies – enabling it to provide support when troubleshooting problems should they occur.
Optimal levels can be provided to other devices by adjusting wordclock output levels
Since the output of the CG-1000 can be set to multiple levels, it can provide optimal signal levels to connected devices.
Checking conditions if problems occur is possible through logging
In addition to being able to check the log on the CG-1000 display, you can also capture the log as a CSV-format file on a USB flash drive.
Self-calibration function enables maintenance by users
