Spread Spectrum Clock Generator
MB88155
■ DESCRIPTION
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 output pin (REFOUT) as well as a modulated output pin (CKOUT) .
