In general, EMI is generated when the clock oscillator outputs a high-frequency signal. To reduce EMI, various components need to be added to the board, increasing the time and resources to complete design and measurement. 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.
