ICS7151A-50

www.DataSheet4U.com ICS7151A-50 Spread Spectrum Clock Generator Description The ICS7151A-50 is a clock generator for EMI (Electromagnetic Interference) reduction. Spectral peaks are attenuated by modulating the system clock frequency. Down or center spread profiles are selectable. Down spread will not exceed the maximum frequency of an unspread clock, and center spread does not change the average operating frequency of the system ICS offers many other clocks for computers and computer peripherals. Consult ICS when you need to remove crystals and oscillators from your board. Features Operating voltage of 3.3 V ±0.3 V Packaged in 8-pin SOIC Available in Pb (lead) free package Input frequency range of 16.5 to 33.4 MHz Output frequency ranges of 8.3 to 16.7 MHz Provides a spread spectrum clock output (±0.5%, ±1.5% center spread; -1.0%, -3.0% down spread) Multiplication rate of x1/2 Advanced, low-power CMOS process Pin compatible with the Fujitsu MB88151-500 Block Diagram VDD S1:0 2 ee DataSh ENS DataSheet4U.com Synthesis PLL Clock CKOUT and Spread Spectrum Circuitry XIN Clock Buffer/ Crystal Ocsillator XOUT External caps required with crystal for accurate tuning of the clock GND DataSheet4U.com MDS 7151A-50 A Integrated Circuit Systems, Inc. ● 1 525 Race Street, San Jose, CA 95126 ● Revision 102005 tel (408) 297-1201 ● www.icst.com DataSheet 4 U .com www.DataSheet4U.com ICS7151A-50 Spread Spectrum Clock Generator Pin Assignment XIN GND S0 S1...
