1 / 9 page ICS7152 MDS 7152 E 1 Revision 012306 Integrated Circuit Systems, Inc. ● 525 Race Street, San Jose, CA 95126 ● tel (408) 297-1201 ● www.icst.com 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 Product Lineup Product Input Frequency Range Modulation Type Modulation Enable Pin ICS7152M-01, ICS7152MI-01 16.6 MHz to 67 MHz Down spread Yes ICS7152M-02, ICS7152MI-02 40.0 MHz to 134.0 MHz ICS7152M-11, ICS7152MI-11 16.6 MHz to 67.0 MHz Center spread ICS7152M-12, ICS7152MI-12 40.0 MHz to 134.0 MHz PLL Clock Synthesis and Spread Spectrum Circuitry SEL FREQ CKOUT GND VDD Clock Buffer/ Crystal Ocsillator XIN XOUT External caps required with crystal for accurate tuning of the clock XENS |
