We're talking jitter with Sandy in the NVE Isolator Applications Center.
Sandy, what is isolator "jitter" and why is it important?
Jitter can be a problem with conventional isolators.
As this shows, jitter is variation
in the pulse edge position of a data stream.
Jitter is just so sad!
Indeed. But NVE's IL700 isolators have a virtually undetectable 50 picoseconds of jitter, making
them ideal for precision audio.
How do isolators help audio circuits?
Two ways. First, galvanic isolation can eliminate hum and noise. And second, low jitter ensures
PCM data phase.
Can you give an example?
Sure. Here's a typical circuit. It's good practice to isolate serial CD, or MP3 data
from the analog sound system. This eliminates ground loops, speaker hum, and high frequency
pickup caused by digital currents in analog paths.
Thanks; that "sounds" good. Where can I get more info?
