Radiated emissions is an important concern in high current switching power supplies. Due to the periodicity of the digital clock signals, the energy concentrates in one particular frequency and also in its odds harmonics, causing EMI issues. SN6507-Q1 implements Spread spectrum clocking (SSC) to reduce the radiated emissions of digital clock signals. The device modulates its internal clock in such a way that the emitting energy is spread over multiple frequency bins. This feature greatly improves the emissions performance of the entire power supply block and hence relieves the system designer from one major concern in isolated power supply design.
