Spread Spectrum Clock Generator

MB88152

s DESCRIPTION

MB88152 is a clock generator for EMI 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 input frequency as Middle Centered and down spread which modulates

so as not to exceed input frequency.

s FEATURES

• Input frequency : 20 MHz to 134 MHz

• Output frequency : 20 MHz to 134 MHz

• Modulation rate : ± 0.5%, ± 1.5% (Center spread), − 1.0%, − 3.0% (Down spread)

• Equipped with crystal oscillation circuit: Range of oscillation 20 MHz to 48 MHz

• Modulation clock output Duty : 40% to 60%

• Modulation clock Cycle-Cycle Jitter : Less than 100 ps

• Low current consumption by CMOS process : 5 mA@24 MHz (Typ-sample, no load)

• Power supply voltage : 3.3 V ± 0.3 V

• Operating temperature : − 40 °C to +85 °C

• Package : SOP 8 pin
