Spread Spectrum Clock Generator

MB88155

■ DESCRIPTION

MB88155 is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radi-

ation noise (EMI) can be attenuated by making the oscillation frequency slightly modulate periodically with the

internal modulator. For modulation, the MB88155 supports both center-spreading and down-spreading. It has a

non-modulated clock output pin (REFOUT) as well as a modulated clock output pin (CKOUT) .

■ FEATURES

• Input frequency :

12.5 MHz to 50 MHz (Multiplied by 1)

12.5 MHz to 20 MHz (Multiplied by 4)

• Output frequency : CKOUT

12.5 MHz to 80 MHz

REFOUT The same as input frequency (not multiplied)

• Modulation rate : 0.5%, 1.0% (center spread) , − 1.0%, − 2.0% (Down spread)

• Equipped with oscillation circuit : range of oscillation 12.5 MHz to 40 MHz (Fundamental oscillation)

40 MHz to 48 MHz (3rd overtone)

• Modulation clock output Duty : 40% to 60%

• Modulation clock cycle − cycle jitter : MB88155-1xx 12.5 MHz to 20 MHz less than 150 ps

MB88155-1xx

20 MHz to 50 MHz less than 100 ps

MB88155-4xx

less than 200 ps

• 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 : 8-pin plastic TSSOP
