Tascam - CG-1800
The CG-1800 is an audio and video clock generator based on a temperature-controlled OCXO crystal oscillator. It continuously measures the external reference clock in order to take countermeasures if the video reference and clock signals shift.
Presentation
During this time, the video reference and clock signals are kept in phase, allowing the reference signal to be re-established without problems, preventing video/audio noise and sound jumps when re-phasing.
