MB88155

Spread Spectrum Clock Generator

MB88155 is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radiation noise (EMI) can

be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator. For modulation, the

MB88155 supports both center-spreading and down-spreading. It has a non-modulated clock output pin (REFOUT) as well as a

modulated clock output pin (CKOUT) .
