Spread Spectrum Clock Generator

DESCRIPTION
MB88154 is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radi-
ation 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 input frequency as Middle
Centered and down spread which modulates so as not to exceed input frequency.
