MB88153 Datasheet (Fujitsu Media Devices) - Spread Spectrum Clock Generator

MB88153, Spread Spectrum Clock Generator

MB88153 is a clock generator for EMI (Electro Magnetic Interference) reduction.

The peak of unnecessary (EMI) can be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator.

It corresponds to both of the center spread which modulates input frequency
