Spread Spectrum Clock Generator

MB88156

■ DESCRIPTION

MB88156 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. The modulation corresponds to the center spread and down spread. The multiplication ratio

can be changed by the pin setting.

Also, the pin can be set whether the modulation is changed. For no modulation, it has the center-non-spread to

fix to the output frequency conforming to the multiplication setting and down-non-spread to fix the output frequency

to center frequency of the down spread.
