ICS7152

www.DataSheet4U.com ICS7152 Spread Spectrum Clock Generator Description The ICS7152-01, -02, -11, and -12 are clock generators for EMI (Electro Magnetic Interference) reduction (see below for frequency ranges and multiplier ratios). Spectral peaks can be attenuated by slightly modulating the oscillation frequency. Both down and center spread profiles are selectable. Center spread maintains an average frequency equal to an unspread clock. Down spread meets maximum frequency specs over the entire modualtion cycle. 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) Advanced, low-power CMOS process Industrial temperature range available Available in Pb (lead) free package Block Diagram VDD SEL FREQ XENS XIN DataShee PLL Clock DataSheet4U.com Synthesis and Spread Spectrum Circuitry CKOUT Clock Buffer/ Crystal Ocsillator XOUT External caps required with crystal for accurate tuning of the clock GND Product Lineup Product Input Frequency Range Modulation Type Modulation Enable Pin ICS7152M-01, ICS7152MI-01 ICS7152M-02, ICS7152MI-02 ICS7152M-11, ICS7152MI-11 ICS7152M-12, ICS7152MI-12 16.6 MHz to 67 MHz 40.0 MHz to 134.0 MHz 16.6 MHz to 67.0 MHz 40.0 MHz to 134.0 MHz Down spread Yes Center spread DataSheet4U.com MDS 7152 E Integrated Circuit Systems, Inc. ● 1 ...
