MB88154 - Spread Spectrum Clock Generator

General Description

MB88154 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.

B88154 ■ DESCRIPTION MB88154 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 input frequency as Middle Centered and down spread which modulates so as not to exceed input frequency. ■ FEATURE • Input frequency : 16.6 MHz to 67 MHz • Output frequency: 16.6 MHz to 67 MHz (One time input frequency) • Modulation rate can select from ± 0.5%, ± 1.0%, ± 1.5% or − 1.0%, − 2.0%, − 3.0%.
