Clock generator
Fujitsu
- ElectroMagnetic interference (EMI:Radiation of electromagnetic ray) becomes a problem with the speed-up/high-density of electronic hardware.
- When the clock generator in an electronic hardware outputs the single frequency, radiation at the frequency and high-frequency becomes large.
- SSCG can suppress the peak lower by oscillation with slightly modulated frequency (Frequency modulation).
1. Large effects on reducing the EMI
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.
