Eliminating Holiday Jitters
By Sandy Templeton
Director, Isolator
Product Development and Applications

Holiday stress can make us jittery, but isolators don't have to.

Audio applications are an example of where minimizing isolator jitter is especially important. NVE’s IL700-Series Isolators have jitter as low as a remarkable as 50 ps, making them ideal for audio circuits or anywhere you want to cure the jitters.

It is extremely desirable to have serial data from a CD or MP3 source isolated from the analog portions of the sound system to eliminate ground loops (speaker hum) and high frequency pickup caused by digital currents flowing in analog current paths:

Low-Jitter Isolated CD Transport Circuit
Almost any isolator can cure your hum and high frequency current noise problems, but non-NVE jittery isolators add phase shift to the PCM data stream for cringe-worthy audio:
