MB88151 - Spread Spectrum Clock Generator

Datasheet Summary

Description

MB88151 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.

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. ■ FEATURES • • • • • • Input frequency : 16.6 MHz to 33.4 MHz Multiplication rate : 1/2, 1, 2, 4 Output frequency : 8.3 MHz to 16.7 MHz, 16.6 MHz to 33.4 MHz, 33.3 MHz to 66.7 MHz, 66.6 MHz to 133.4 MHz Modulation rate : ± 0.5%, ± 1.
