Spread Spectrum Clock Generator
MB88155
■
DESCRIPTION
MB88155 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. For modulation, the MB88155 supports both center-spreading and down-spreading. It has a
non-modulated clock output pin (REFOUT) as well as a modulated clock output pin (CKOUT) .
