Product Description

The P2040A is a versatile spread spectrum frequency modulator designed specifically for digital flat panel applications. The P2040A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P2040A 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.

Features

◾ FCC approved method of EMI attenuation.
