SHARE THIS PRODUCT:

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

An external input connector that supports a 10MHz signal enables the CG-1000 to be connected to a rubidium clock or GPS clock for 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

The CG-1000 constantly measures the external reference clock. In devices that do not have built-in countermeasures, and the master clock signal drops out, sound might skip during the dropout - and again during recovery.
In the CG-1000, if the clock drops out, a substitute reference clock signal is maintained with a high-performance holdover.
So, restoration of synchronization to the reference signal can occur without glitches - preventing audio noise and skipping sounds when recovering from a dropout.

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
