P1817A, P1817B Product Preview Low-Power Mobile VGA EMI Reduction IC Description The P1817 is a versatile spread spectrum frequency modulator designed specifically for input clock frequencies. The P1817 reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P1817 allows significant system cost savings by reducing the number of circuit board layers, ferrite beads, shielding and other passive ponents that are traditionally required to pass EMI regulations. The P1817 modulates the output of a single PLL in order to “spread” the bandwidth of a synthesized clock, and more importantly,...
