OCXO Clocks

Sound essentially consists of analog signals, which processing is associated with the problems of attenuation, noise, and deterioration. These issues are addressed when the original sound passes through an analog-to-digital converter (ADC) after which the resulting data can be distributed on CDs or via networks as digital sound. Following, these data are processed using a digital-to-analog converter (DAC) in the end user's digital audio device and output as analog sound.

In the digitization of analog signals, sampling is carried out at a certain frequency. To reproduce sound with the highest fidelity possible, higher sampling frequencies and bit rates are required. Today's high-resolution audio sources are characterized by sampling frequencies and bit rates superior to those used for CDs, enabling digitalization for true high-fidelity audio reproduction. Faithful reproduction of high-resolution audio sources requires precise digital signal processing and analog sound output with reduced deterioration of the sound source in the digital audio device.

This conversion accuracy depends on the noise characteristics (i.e., frequency components outside the target frequency) of the clock frequency of the audio device used. To enhance the sound reproducibility Pink Faun OCXO clocks are designed with superior phase noise characteristics (i.e., low jitter).
