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 output pin (REFOUT) as well as a modulated output pin (CKOUT) .
■ FEATURES
Input frequency :
12.5 MHz to 50 MHz (Multiplied by 1)
12.5 MHz to 20 MHz (Multiplied by 4)
Output frequency : CKOUT
12.5 MHz to 80 MHz
REFOUT
The same as input frequency (not multiplied)
Modulation rate :
± 0.5%, ± 1.0% (center spread) , 1.0%, 2.0% (Down spread)
Equipped with oscillation circuit : range of oscillation 12.5 MHz to 40 MHz (Fundamental oscillation)
40 MHz to 48 MHz (3rd overtone)
Modulation clock output Duty : 40
% to 60%
