Product Description

The P2040C is a selectable spread spectrum frequency modulator designed specifically for digital flat panel applications. The P2040C reduces electromagnetic interference (EMI) at the clock source which provides system wide reduction of EMI of all clock dependent signals. The P2040C allows significant system cost savings by reducing the number of circuit board layers and shielding that are traditionally required to pass EMI regulations.
