MB88151 Datasheet Spread Spectrum Clock Generator

Manufacturer: Fujitsu Semiconductor Limited

Overview: .. FUJITSU SEMICONDUCTOR DATA SHEET DS04-29116-2E Spread Spectrum Clock Generator.

General 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.

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.
