Spread Spectrum:
When the system clock generator pulses, the
-
Enabled
extreme values of the pulse generate excess
-
Disabled
EMI. Enabling pulse spectrum spread modula
tion changes the extreme values from spikes
to flat curves, thus reducing EMI. This benefit
may in some cases be outweighed by
problems with timing-critical devices, such as
a clock-sensitive SCSI device.
