Tascam CG-1800 Video Sync/Master Clock Generator

Become the cornerstone of precision and stability in your video and audio synchronization systems with the Tascam CG-1800 Video Sync/Master Clock Generator. This sophisticated device is engineered around an OCXO (oven-controlled crystal oscillator), celebrated for its exceptional precision and resistance to environmental temperature fluctuations. With an impressive clock frequency precision of 0.01 ppm, the CG-1800 surpasses the capabilities of a TCXO (temperature-compensated crystal oscillator), making it essential for constructing high-precision synchronization systems.

The Tascam CG-1800 ensures word output frequency stability of +/-0.005 ppm or less per day, guaranteeing consistent and reliable performance. Its unique TASCAM circuit design effectively minimizes external clock jitter, incorporating a high-performance video clock generator. This generator is crafted with an FPGA (Field-Programmable Gate Array) and a PLL (phase-locked loop) circuit featuring a discrete filter, ensuring a stable clock signal for both video and word outputs, thereby enhancing overall system stability.

The CG-1800 is equipped with a glitch-free relock circuit that eliminates noise and skipping sounds caused by master clock dropouts. Its versatile output options include 12 word clock outputs, 4 video outputs, 2 AES3/AES11 outputs, and 2 S/PDIF outputs, making it an invaluable asset for large-scale audio/video synchronization systems and a wide array of other applications. Notably, two of the 12 word outputs support x2Fs, x4Fs, and 256Fs output, ensuring compatibility with systems running ProTools and other DAW software.

Beyond its high-performance capabilities, the CG-1800 serves as a reliable troubleshooting tool. It features an analyzer function for measuring output device termination, input level, and input frequencies. Additionally, a logging function allows issues to be documented and saved in a CSV file format on a USB flash drive, facilitating easy problem resolution.

Understanding that crystal oscillators change over time, the CG-1800 is equipped with a self-correction function. This feature allows users to perform maintenance using an external signal input and straightforward operations. The device's durability is further enhanced by Amphenol BNC connectors on the chassis, which utilize nuts for coupling. Each connector is mounted on a separate circuit board, providing excellent resistance to cable twisting and pulling, while suppressing interference between connectors.

The Tascam CG-1800 Video Sync/Master Clock Generator is the latest addition to TASCAM's esteemed line of professional digital products, embodying cutting-edge digital clocking technology. Elevate your synchronization systems with the unmatched precision and reliability of the CG-1800.
