www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-29116-2E Spread Spectrum Clock Generator MB88151 ■ DESCRIPTION MB88151 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 Input frequency : 16.6 MHz to 33.4 MHz Multiplication rate : 1/2, 1, 2, 4 Output frequency : 8.3 MHz to 16.7 MHz, 16.6 MHz to 33.4 MHz, 33.3 MHz to 66.7 MHz, 66.6 MHz to 133.4 MHz Modulation rate : ± 0.5%, ± 1.5% (Center spread), − 1.0%, − 3.0% (Down spread) Equipped with oscillation circuit : Range of oscillation 16.6 MHz to 33.4 MHz Modulation clock output Duty : 40% to 60% (Continued) ■ PACKAGE 8-pin plastic SOP (FPT-8P-M02) MB88151 (Continued) Modulation clock Cycle-Cycle Jitter MB88151-100, 200 : Less than 100 ps MB88151-400 : Less than 150 ps MB88151-500 : 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 : SOP 8-pin ■ PRODUCT LINEUP MB88151 has four kinds of multiplication type.
