Low Jitter Clock Generation for Digital Audio

Brief Event Description: The demands of modern audio converters make low-jitter audio clocks a critical requirement if high-performance is to be achieved. It is now possible to find affordable ADCs and DACs that approach or exceed 130dB SNR and -120dB THDN. Run of the mill clock generators will not cut it for performance at this level. In this presentation Paul will show how jitter affects audio, how much jitter is allowed given an audio-quality target, what kind of clock generators can achieve these specs, and how to measure jitter. Since most pro-audio systems need to interface to the outside world for timing, He will also talk about clock recovery and jitter attenuation. Finally, he’ll tie this all together with measurements on a real product that achieves suitably stratospheric performance
