New Rubicon DAC Uses Atomic Clock for Jitter-Correction

Stefan Mileschin · 25th April 2012, 06:27

A new DAC by Rubicon, the Rubicon Antelope, seeks to address the problem of jitter using a rubidium atomic clock instead of a crystal oscillator. Modern electronics rely on oscillators and clock-generators to time the flow of everything from signals to well-structured packets of data. Often the accuracy of these could impact on signal quality (think of a packet "missing the bus" due to bad timing), during digital to analog conversion. External DACs tend to suffer jitters during digital to analog conversion, which could ruin the experience for extreme-Audiophiles.

Rubicon used the most accurate clock generation technique known to man, by implementing a rubidium atomic clock. This clock, Rubicon claims, is 100,000 times more stable than conventional crystal oscillators. Although it sounds gimmicky to the mainstream, atomic clock-based equipment very much are used in big-budget professional mastering studios. Other features include 64-bit acoustically-focused clocking jitter management technology; 384 kHz D/A and A/D converters; ultra-linear, dual stage headphone amps; de-jittered audio S/PDIF output; DLNA streaming capabilities through an Ethernet interface.
