MB88151 Datasheet (Fujitsu Media Devices) - Spread Spectrum Clock Generator

MB88151, Spread Spectrum Clock Generator

MB88151 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.

It corresponds to both of the center spread which modulates
