DATA SHEET

Spread Spectrum Clock Generator

MB88162

■ DESCRIPTION

MB88162 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

• Multiplication rate : 1, 4

• Output frequency : 12 MHz to 28 MHz (Multiplied by 1), 80 MHz to 168 MHz (Multiplied by 4)

• Modulation rate : no modulation,

± 0.5%, ± 1.0%, ± 2.0%, − 1.0%, − 2.0%, − 4.0% (The terminal can be selected.)

• Equipped with oscillation circuit : Range of oscillation 12 MHz to 42 MHz

• Built-in oscillation stabilization capacitance : 4 pF (Typ)

• Modulation clock output Duty : 40

% to 60%

• Low power consumption by CMOS process : 7.0 mA (24 MHz : no load, Typ-sample, Typ-condition)

• Power supply voltage : 2.7 V to 3.6 V (Multiplied by 1), 3.0 V to 3.6 V (Multiplied by 4)

• Operating temperature :

− 40 °C to + 85 °C
