DATASHEET SPREAD SPECTRUM CLOCK GENERATOR ICS7152A Description Features The ICS7152A-02 and -11 are clock generators for EMI Operating voltage of 3.3 V 0.3 V (Electromagnetic Interference) reduction (see below for Packaged in 8-pin SOIC frequency ranges and multiplier ratios). Spectral peaks are Input frequency range of 16.6 to 134.0 MHz attenuated by modulating the system clock frequency. Down or center spread profiles are selectable. Down Output frequency range of 16.6 to 134.0 MHz spread will not exceed the maximum frequency of an Provides a spread spectrum clock output (0.5%, 1.5% unspread clock, and center spread does not change the center spread -1.0%, -3.0% down spread) average operating frequency of the system Low cycle-to-cycle jitter - less than 100 ps IDT offers many other clocks for computers and computer Advanced, low-power CMOS process peripherals. Consult IDT when you need to remove crystals Industrial and commercial temperature ranges and oscillators from your board.
