ICS7152A

www.DataSheet4U.com ICS7152A Spread Spectrum Clock Generator Description The ICS7152A-02 and -11 are clock generators for EMI (Electromagnetic Interference) reduction (see below for frequency ranges and multiplier ratios). 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 Input frequency range of 16.6 to 134.0 MHz Output frequency range of 16.6 to 134.0 MHz Provides a spread spectrum clock output (±0.5%, ±1.5% center spread; -1.0%, -3.0% down spread) Low cycle-to-cycle jitter - less than 100 ps Advanced, low-power CMOS process Industrial and commercial temperature ranges Available in Pb (lead) free package Pin compatible with Fujitsu MB88152-102 and -111 Block Diagram VDD DataShee SEL FREQ XENS XIN DataSheet4U.com PLL Clock Synthesis and Spread Spectrum Circuitry Clock Buffer/ Crystal Ocsillator CKOUT XOUT External caps required with crystal for accurate tuning of the clock GND Product Lineup Product Input Frequency Range Modulation Type Modulation Enable Pin ICS7152AM-02, ICS7152AMI-02 ICS7152AM-11, ICS7152AMI-11 40.0 ...
