Commercial temperature PCS3P2537A PCS3P2537A modulates the output of www.DataSheet4U.com a single 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.
