• 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.
• *2 Use of the self-calibration function requires preparation of a separate PPS-output 10MHz oscillator with a built-in GPS antenna.

High-precision synchronization systems can be createdInternal clock uses a high-precision OCXO that is not influenced by the temperature of the environmentThe crystal oscillator is the heart of the clock generator, In the CG-1000, 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*, 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 precisionAn external input connector that supports a 10MHz signal enables the CG-1000 to be connected to a rubidium clock or GPS clock for even higher precision.Abundant Input and Output Connectors Support Use in Large-scale Audio Synchronization SystemsNumerous output connectors, including 12 word clock outputsIn addition to 12 word clock outputs, the digital outputs include 2 AES3/AES11 and 2 S/PDIF outputs, making this unit useful for large-scale audio synchronization systems, and a wide variety of other applications.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 StabilityJitter management circuit provides stable clockExternal clock jitter is reduced using an original TASCAM circuit design that incorporates featuring an FPGA (Field Programmable Gate Array) and a PLL (phase-locked loop) circuit with a discrete filter.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 recoveryThe CG-1000 constantly measures the external reference clock. In devices that do not have built-in countermeasures, and the master clock signal drops out, sound might skip during the dropout – and again during 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.Analyzer function that can measure input frequenciesIn the installation of broadcasting and large-scale post-production studios, numerous connected devices and complicated wiring are common.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 levelsDepending on the routing of wiring and the receiving devices, signal levels could be reduced – resulting in proper reception failures.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 loggingOne function that enables identification of the causes of trouble is the logging function.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 usersSince crystal oscillators change over time, regular calibration is necessary. In order to avoid problems that could lead to broadcast trouble, timely inspections and regular maintenance are required. The CG-1000 has a self-correction function, enabling users to conduct maintenance using external signal input* and simple operations.Durable nut-coupling Amphenol BNC connectorsSince the Amphenol BNC connectors use nuts for coupling, they are extremely resistant to pulling, twisting and multiple connect-disconnect cycles.Each connector has an independent circuit board to prevent contact failures due to twisting and repeated useThe construction uses a single circuit board for each connector. This provides excellent resistance to the twisting and pulling of cables and suppresses interference between connectors.Features:
