February 2005 www.DataSheet4U.com ASM3P2508A Peak EMI Reducing Solution rev 1.3 Features Generates an EMI optimized clocking signal at output. Input frequency – 14.31818 MHz. Frequency outputs: o o 120 MHz (modulated) - default. 72 MHz (modulated) or 48 MHz (modulated) selectable via I2C ± 1% Centre spread. Modulation rate: 40 KHz. Byte Write via I2C Supply voltage range 3.3V ± 0.3V. Available in 8-pin SOIC Package. Available in Commercial and Industrial Temperature ranges. The ASM3P2508A allows significant system cost savings by reducing the number of circuit board layers and shielding that are required to pass EMI regulations. The ASM3P2508A modulates the output of PLL in order to spread the bandwidth of a synthesized clock, thereby decreasing the peak amplitudes of its harmonics.
