DESCRIPTION
The CG-1000 is a master clock generator based on a high-precision OCXO – Oven Controlled Crystal Oscillator – with jitter management and glitch-free relocking for the best clock precision available, ideal for recording studios, sound engineers and musicians
The internal clock employs the high-precision OCXO that is not impacted by environment temperature
The CG-1000 employs a high-precision OCXO (oven-controlled crystal oscillator) that boasts a clock frequency precision of ±0.01ppm*1 and a frequency stability of ±0.005ppm per day. The jitter management circuit developed by TASCAM reduces external clock jitters, enabling a stable clock signal to video and word outputs. 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.

Input connector that supports 10MHz signal – allowing the creation of systems with even higher precision
Designed for High Reliability and Dependable Stability
External clock jitter is reduced using an original TASCAM circuit design that incorporates 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 word outputs, improving system stability.
Glitch-free relocking circuit prevents noise and skipping during clock dropouts and recovery
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 audio synchronization systems
- AES3 and AES11 signals can also be used for external master clock input sources
- Analyzer function that can measure input frequencies
- Optimal levels can be provided to other devices by adjusting wordclock output levels
- Self-calibration function using an external oscillator (Atomic/GPS 10MHz, GPS PPS)*Use of the self-calibration function requires the use of a separate PPS-output 10MHz oscillator with a built-in GPS antenna
