TASCAM CG-1000

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

The CG Series includes three distinct models tailored to different types of studios. The CG-2000 is designed for the needs of broadcasting and post production, the CG-1800 for small to large-scale video/audio synchronization systems, and the CG-1000 for recording studios, live sound applications and professional musicians.

The crystal oscillator is the heart of the clock generator. In each model of the CG Series, 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*1, 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 FPGA*2 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. Of the (12) word outputs, two also support x2Fs, x4Fs and 256Fs output – enabling them to be used in systems with ProTools and other DAW software.

The CG Series has multiple functions to support maintenance, and the identification of issues if problems occur. The analyzer function measures output device termination, input level measurement (for CG-2000 and CG-1800), and the measurement of input frequencies. These built-in features enable the devices to provide troubleshooting support. Additionally, a logging function enables issues to be listed, and saved to a CSV file format on a USB flash drive.

Since crystal oscillators change over time, regular calibration is necessary. In order to avoid possible sync problems, timely inspections – along with regular maintenance is required. The CG Series has a self-correction function, enabling users to conduct maintenance using an external signal input*3 and simple operations.

Amphenol BNC connectors on the chassis use nuts for coupling – making them very durable, Also, a single circuit board is used for each connector – providing excellent resistance to the twisting and pulling of cables, and the suppression of interference between connectors.

The CG Series is the latest in the line of innovative TASCAM professional digital products – engineered with the latest digital clocking technology.

Input connector that supports 10MHz signal – allowing the creation of systems with even higher precision

An 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 Systems

Numerous output connectors, including 12 word clock outputs

In 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.

Designed for High Reliability and Dependable Stability

Jitter management circuit provides stable clock

External 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 recovery

The 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.

Multiple Functions Support Maintenance and Identification of Issues If Problems Occur

Analyzer function that can measure input frequencies

In 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 levels

Depending 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 logging

One 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 users

Since 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.

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

Designed for Durability

Durable nut-coupling Amphenol BNC connectors

Since 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 use

The 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.
