1 / 22 page DS04-29127-1E FUJITSU SEMICONDUCTOR DATA SHEET Copyright©2007 FUJITSU LIMITED All rights reserved ASSP Spread Spectrum Clock Generator MB88151A ■ 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 MB88151A- 100/101 (multiply-by-1) MB88151A- 200/201 (multiply-by-2) MB88151A- 400/401 (multiply-by-4) MB88151A- 500/501 (multiply-by-1/2) MB88151A- 800/801 (multiply-by-8) Input frequency/ Output frequency 16.6 MHz to 33.4 MHz/ 16.6 MHz to 33.4 MHz 16.6 MHz to 33.4 MHz/ 33.2 MHz to 66.8 MHz 16.6 MHz to 33.4 MHz/ 66.4 MHz to 133.6 MHz 16.6 MHz to 33.4 MHz/ 8.3 MHz to 16.7 MHz 8.3 MHz to 16.7 MHz 66.4 MHz to 133.6 MHz Modulation clock cycle-cycle jitter Less than100 ps Less than 100 ps Less than 150 ps Less than 200 ps Less than 150 ps |
