Spread Spectrum Clock Generator
MB88161
■ DESCRIPTION
MB88161 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.
■ FEATURES
• • • • • • • • • • • • Input frequency : 20 MHz to 28 MHz (Multiplied by 1), 14 MHz to 40 MHz (Multiplied by 2) Multiplication rate : 1, 2 Output frequency : 20 MHz to 28 MHz (Multiplied by 1), 28 MHz to 80 MHz (Multiplied by 2) Modulation rate : no modulation, ± 0.5%, ± 1.0%, ± 2.0%, − 1.0%, − 2.0%, − 4.0% (The terminal can be selected.
