The internal clock employs the high-precision OCXO that is not impacted by environment temperature This provides excellent resistance to the twisting and pulling of cables and suppresses interference between connectors.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 The construction uses a single circuit board for each connector. Since the Amphenol BNC connectors use nuts for coupling, they are extremely resistant to pulling, twisting and multiple connect-disconnect cycles.Įach connector has an independent circuit board to prevent contact failures due to twisting and repeated use The CG-1000 has a self-correction function, enabling users to conduct maintenance using external signal input and simple operations.ĭurable nut-coupling Amphenol BNC connectors In order to avoid problems that could lead to broadcast trouble, timely inspections and regular maintenance are required. ![]() Since crystal oscillators change over time, regular calibration is necessary. Self-calibration function enables maintenance by users 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. One function that enables identification of the causes of trouble is the logging function. Since the output of the CG-1000 can be set to multiple levels, it can provide optimal signal levels to connected devices.Ĭhecking conditions if problems occur is possible through logging Optimal levels can be provided to other devices by adjusting wordclock output levelsĭepending on the routing of wiring and the receiving devices, signal levels could be reduced - resulting in proper reception failures. 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. In the installation of broadcasting and large-scale post-production studios, numerous connected devices and complicated wiring are common. So, restoration of synchronization to the reference signal can occur without glitches - preventing audio noise and skipping sounds when recovering from a dropout.Īnalyzer function that can measure input frequencies In the CG-1000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover. 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. The CG-1000 constantly measures the external reference clock. Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery This enables a stable clock signal to be provided to the word outputs, improving system stability. ![]() Jitter management circuit provides stable clockĮxternal 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. 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. 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. Numerous output connectors, including 12 word clock outputs Input connector that supports 10MHz signal - allowing the creation of systems with even higher precisionĪn 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. 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. The 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. ![]() The Tascam CG-1000 master clock generator is for recording studios, live sound applications and professional musicians.
