P3I2005A General Purpose Peak EMI Reduction IC Product Description P3I2005A is a versatile, 3.3 V / 5 V, 1x spread spectrum frequency modulator designed to reduce electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The device allows significant system cost savings by reducing the number of circuit board layers ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations. P3I2005A modulates the output of a PLL in order to “spread” the bandwidth of a synthesized clock, and more importantly, decreases the peak amplitudes of its harmonics. This results in significantly lower system EMI compared to the typical narrow band signal produced by oscillators and most frequency generators. Lowering EMI by increasing a signal’s bandwidth is called ‘spread spectrum clock generation’. P3I2005A accepts an input from an external reference clock and locks to a 1x modulated clock output. Two logic pins S0 and D_C enable selecting one of the 4 different frequency deviations. Refer Deviation Selection table. Frequency Range Selection pin enables operation in one of the two frequency ranges. P3I2005A operates over a supply voltage range of 5 V / 3.3 V. P3I2005A is available in 8 Pin SOIC Package.
