MB88161 Spread Spectrum Clock Generator

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 b.
