Spread Spectrum Clock Generator
MB88151A
■
DESCRIPTION
MB88151A 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 frequency in modulation off
as Middle Centered and down spread which modulates so as not to exceed frequency in modulation off.
