Spread Spectrum Clock Generator

Fujitsu 

MB88156

• Center spread

Spectrum is spread (modulated) by centering on the non-spread frequency.

Radiation level

Modulation width 2.0%

−1.0%

+1.0%

Non-spread frequency

Example of center spread modulation rate ±1.0% (2.0%)

• Down spread

Spectrum is spread (modulated) below the non-spread frequency.

Radiation level

Modulation width 2.0%

Frequency

−2.0%

Non-spread frequency

Example of down spread modulation rate − 2.0%

Frequency

• Down-non-spread

Slightly lowering the output frequency with modulation stopped fixes it to the center frequency for down spreading.

Radiation level

−1.0%

Down frequency

Frequency

Frequency of multiplication ratio setting

Example of down-non-spread −1.0%
