P1P8160A Low Jitter Clock Generator and Peak EMI Reduction IC Product Description P1P8160A is a versatile low jitter clock generator and 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. P1P8160A 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’. P1P8160A accepts an input from either a 27 MHz fundamental Crystal or from an external reference clock and generates a 100 MHz Spread Spectrum clock. The device also features a 27MHz reference clock output. Two Tri−level logic pins, SS1% and SS2% enables selecting one of the eight different frequency deviations along with SSOFF. Refer to Frequency Deviation Selection table. P1P8160A operates over a supply voltage range of 3.3 V ± 10%. P1P8160A is available in a 10 Pin WDFN (3 mm x 3 mm) package, over temperature range −10°C to +85°C.
