Tascam CG-2000 Video Sync/Master Clock Generator

The Tascam CG-2000 Video Sync/Master Clock Generator is based on a high-precision OCXO (oven-controlled crystal oscillator) that boasts a clock frequency precision of ±0.01ppm and a frequency stability of ±0.005ppm per day. With redundancy of both the power supply and the video/audio clock, as well as many other functions, the CG-2000 meets the strict demands of broadcasting and post production.

The Tascam CG-2000 Video Sync/Master Clock Generator's internal clock employs the high-precision OCXO that is not impacted by environment temperature. In addition, the Tascam CG-2000 is equipped with an external input connector that supports a 10MHz signal, allowing it to be connected to a rubidium clock or GPS clock, when possible, for even higher precision for the system. The jitter management circuit developed by TASCAM reduces external clock jitters, enabling a stable clock signal to video and word outputs, while 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.

Designed for High Reliability and Dependable Stability
Power supply redundancy with two power supply circuits. With two power supply circuits, the Tascam CG-2000 features redundancy to prevent mishaps caused by power outages. Redundant video reference/word clock input. With two inputs each for video reference and world clock signals, there is redundancy to prevent problems due to external clock interruption. Jitter management circuit provides stable clock. External clock jitter is reduced using an original TASCAM circuit design that incorporates a high-performance video clock generator device, 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 video/word outputs, improving system stability. Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery. The Tascam CG-2000 constantly measures the external reference clock. In devices that do not have built-in countermeasures, and the master clock signal drops out, the video reference and word clock signals could become out of phase, and sound might skip during the dropout - and again during recovery. In the Tascam CG-2000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover. During this time, the video reference and word clock signals are kept in-phase, so restoration of synchronization to the reference signal can occur without glitches - preventing video/audio noise and skipping sounds when recovering from a dropout.

Abundant Input and Output Connectors Support Use in Large-scale Audio/Video Synchronization Systems
Numerous output connectors, including 12 word clock outputs - 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 2×Fs, 4×Fs and 25×6Fs output – enabling them to be used in systems with ProTools and other DAW software. Supports input and output of a variety of video signal formats - including NTSC, PAL and HD Tri-level. Analog NTSC/PAL and digital HD Tri-level video signal formats are supported.

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.
