TASCAM / CG-1800

A clock generator for small to large-scale post-production. High-precision OCXO for internal clock that is unaffected by ambient temperature. A proprietary jitter management circuit reduces external clock jitter and provides a stable clock for video/word output. Self-calibration function using an external oscillator. User maintenance is possible.

■Clock Generator

The CG series is a lineup of master clock generators that allows you to choose the optimal model for your application and environment: the CG-2000 for broadcast stations and large-scale post-production facilities, the CG-1800 for small to large-scale post-production facilities, and the CG-1000 for recording studios, sound engineers, and musicians.

■Features
- High-precision OCXO (oven-controlled crystal oscillator) for the internal clock, unaffected by ambient temperature.
- A 10MHz external input terminal allows for the construction of even more accurate systems.
- Jitter management circuit provides a stable clock.
- Glitch-free relock circuit prevents noise and audio interruptions during clock dropout and recovery.
- A wide range of output terminals, including 12 word outputs, enable support for large-scale video/audio synchronization systems.
- Supports a variety of video signal inputs and outputs, including NTSC/PAL/HD Tri-level.
- AES3 and AES11 can also be selected as external master clock sources.
- Analyzer function allows measurement of output device termination.
- Word clock output level adjustment function allows for optimal signal supply to devices.
- Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS).
* To use the calibration function, a separate 10MHz PPS output oscillator with a built-in GPS antenna is required.
