The Fujitsu Spread Spectrum Clock Generator (SSCG) reduces radiated EMI that results from system clock operation. It minimizes the need for other shielding components like bypass capacitors, choke coil and ferrite bead, resulting in system-level cost savings.
The Fujitsu SSCG family includes a variety of devices that modulate clock frequencies to attenuate peak emissions in computers,
printers, MP3 players, cell phones, and other products that operate at increasingly higher frequencies. Peak radiation noise
is reduced by slightly modulating oscillation frequencies with the internal modulator.
SSCG can suppress the peak of unnecessary radiation by modulating the frequency. It is effective for not only the oscillation frequency of clock (basic wave) but also higher harmonic wave.
