■ DESCRIPTION

MB88151A 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.

■ FEATURES

• Modulation rate : ± 0.5, ± 1.5 (Center spread), − 1.0, − 3.0 (Down spread)

• Equipped with oscillation circuit : Range of oscillation 8.3 MHz to 33.4 MHz

• Modulation clock output Duty : 40 to 60

• Low current consumption by CMOS process : 5 mA (24 MHz : Typ-sample, no load)

• Power supply voltage : 3.3 V ± 0.3 V

• Operating temperature : − 40 °C to + 85 °C

• Package : SOP 8-pin
