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
