The CG-1800 master clock generator generates NTSC, PAL and HD Tri-level video clock – as well as word clock through BNC, AES/EBU and S/PDIF outputs – ensuring compatibility with any synchronization system
Features
- Internal clock uses a high-precision OCXO (oven-controlled crystal oscillator) that is not influenced by the temperature of the environment
- External input connector that supports 10MHz, allowing creation of systems with even higher precision
- Jitter management circuit provides stable clock
- Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
- Numerous output connectors, including (12) word clock outputs, enabling the use in large-scale video/audio synchronization systems
- Supports input and output of a variety of video signal formats, including NTSC, PAL and HD Tri-level
- AES3 and AES11 signals can also be used for external master clock input sources
- Up to (4) system settings can be saved to buttons for recall, and saved settings can be imported and exported via USB
