... MB88153 DESCRIPTION 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 as Middle Centered and down spread which modulates so as not to exceed input frequency ...
