It is a well-known fact among audiophiles that the clock signal is the foundation for all digital signal processing. For example, digital signals, such as PCM, are divided extremely finely into tens of thousands of parts per second along the time axis. If that fundamental time axis fluctuates during the process of D/A conversion it is much more difficult to render an analogue audio waveform that is identical to the original. This is all the more true with DSD audio signals that function at MHz speeds in the time axis. For this reason, having as accurate a clock signal as possible is very important for the re-creation of digital audio signals, particularly HiRes files that use ultra high sampling-rates, such as DSD 22.5MHz or PCM 768kHz.
At the heart of the master clock generator is a crystal oscillator, encased in a temperature- controlled box, the "oven", to maintain the best and stable performance under an ideal temperature condition for crystal oscillation. This oven-controlled crystal oscillator (OCXO, for short) generates an extremely accurate 10MHz clock signal which is within ±3 ppb of frequency-temperature characteristics and within ±0.1 ppm of frequency precision.
The elegant analogue gauge on the front panel gives a visual indication of the status of the internal crystal oscillator at all times..
The CG-10M is a master clock generator that brings out the best performance from USB DACs, network players, CD players and any other kind of device that supports a 10MHz clock input.
New Reference OCXO an Oven-controlled Crystal Oscillator
Since temperature has a huge effect on accuracy of the crystal oscillator minimising temperature changes and maintaining it at an ideal level are extremely important in order to generate an accurate clock signal. The CG-10M employs an innovative oven-controlled crystal oscillator the TEAC Reference OCXO to reduce oscillation frequency fluctuations caused by temperature changes.
A Class-Leading Ultra High-Precision Clock
Thanks to the TEAC Reference OCXOn the CG-10M delivers an ultra high-precision 10MHz clock signal – within ±3 ppb of frequency-temperature characteristics and within ±0.1 ppm of frequency precision – to USB DACs and digital players. A unique laser-engraved serial number and the TEAC Reference OCXO logo on every OCXC case is proof of the rigorous quality inspection undertaken during the manufacturing process.
Four BNC clock output connectors
Four gold-plated BNC connectors (50 ohms) are provided to deliver clock signals to multiple devices. Up to four devices that support a 10MHz input may be connected simultaneously including USB DACs network players and SA-CD players.
