MB88153 - Spread Spectrum Clock Generator

Datasheet Summary

Description

MB88153 is a clock generator for EMI (Electro Magnetic Interference) reduction.

The peak of unnecessary (EMI) can be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator.

Features

  • D = 12.5 kHz (Typ).
  • 1.0% modulation rate, Example of down spread CKOUT output frequency Frequency at modulation OFF Time.
  • 0.5 %.
  • 1.0 % fMOD.

The peak of unnecessary (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 • • • • • • • • • • Power down pin : 600 µA (Max) consumption current at power down Input frequency : 16.6 MHz to 134 MHz Output frequency : 16.6 MHz to 134 MHz (One-fold input frequency) Modulation rate can select from ± 0.5%, ± 1.5% − 1.0% or − 3.0%.
