The P2042A is a versatile spread spectrum frequency modulator designed specifically for digital flat panel applications. The P2042A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P2042A 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.

• Generates a low EMI spread spectrum clock of the input frequency
