Spread Spectrum Clock Generator:SSCG
- Concern around electromagnetic interference (EMI) (1)from the electrical equipment is increasing because of higher operation frequency and higher integration of the semiconductor devices.
- When the clock generator in the equipment generates the clock signal, electromagnetic radiations are observed not only at the main clock frequency but also at the harmonic spurious frequencies.
SSCG can reduce EMI(1) radiations by slightly clock modulating.
