P2041A

Versatile EMI Reduction IC

Description

The P2041A is a selectable spread spectrum frequency modulator

designed specifically for PC peripheral and embedded controller

markets. The P2041A reduces electromagnetic interference (EMI) at

the clock source which provides system wide reduction of EMI of all

clock dependent signals. The P2041A allows significant system cost

savings by reducing the number of circuit board layers and shielding

that are traditionally required to pass EMI regulations.

The P2041A uses the most efficient and optimized modulation

profile approved by the FCC and is implemented in a proprietary

all−digital method.

The P2041A modulates the output of 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.

Lowering EMI by increasing a signal’s bandwidth is called ‘spread

spectrum clock generation.’
