The SM532 is well suited for a wide range of digital system applications that require a reduction of radiated energy. This unwanted radiated energy is usually found in the odd harmonics of digital system clocks. By modulating the frequency of the digital clock, measured EMI at the fundamental and harmonic frequencies is greatly reduced. This reducti...
