This document describes about MB88155, it's 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) .
