T1 10MHz Time Reference

Timing in digital systems is the key to carry and to faithfully convert digital audio content. Why so? Let’s imagine that a digital to analog converter chip is fed from a clock containing a high level of phase noise, otherwise known as jitter in the time domain. Instead of being evenly spaced in time, the digital audio information converted to the analog domain is spread randomly around the ideal time, introducing undesired artifacts. The better the clock source, the lesser the phase noise, the more precise the conversion.

An ultra-low phase noise, high accuracy 10MHz oven controlled oscillator (OCXO) forms the heart of the T1, CH Precision’s first clock generator.

Features

Outputs
