:Clock Dithering - some more information
I followed the recent discussion threads on this topic, but it is not in my
main stream of interest. However, I just remembered an extensive report I
had seen on the subject.
The report is Investigation into possible effects resulting from dithered

Hi Cyril,
I have a very good (EMC-wise) experience with clock dithering.
I started using the Spread Spectrum Clock Generation (SSCG) technique
(patented by Lexmark) in 1995 when I worked for my previous company.
We made printers and one of our main customers was IBM. They pushed us to
use

Be careful. IBM (perhaps Lexmark now) holds a patent on certain aspects of
this technology.
