General Description

IMI SG521/22/24/28 products are Spread Spectrum Clock Generators designed to reduce the high levels of Electromagnetic Interference (EMI) found in high-speed digital systems.

By using a modulated clock as the source for all system clocks and timing signals, the amount of radiated energy (EMI) throughout the system is greatly reduced.

Energy reduction is related to the harmonic frequency, such that the higher the frequency the greater the energy reduction.
