Clock Dithering for EMI Reduction by Kesavant Tkesavan is a document available to read on EtoBox.

What is Clock Dithering for EMI Reduction about?

The document discusses frequency modulation of system clocks through clock dithering as a technique for reducing electromagnetic interference (EMI) emitted from integrated circuits. It reviews different approaches to clock dithering used at HP, including square wave and triangle wave modulation. Square wave modulation distributes the clock frequency more widely but introduces greater cycle-to-cycle jitter, while triangle wave modulation reduces jitter but may not lower frequencies as much.
