Spread Spectrum Clock Generator
MB88161
■ DESCRIPTION
MB88161 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.
■ 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.)
• Equipped with oscillation circuit : Range of oscillation 10 MHz to 40 MHz
• Built-in oscillation stabilization capacitance : 4pF (Typ)
• Modulation clock output Duty : 40% to 60%
• Modulation clock Cycle-Cycle Jitter : Less than 100 ps
• Low current 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
• Operating temperature : − 40 °C to + 85 °C
• Package : BCC 18-pin
