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.’
Applications
The P2041A is targeted towards the embedded controller market
and PC peripheral markets including scanners, MFP’s, printers, PDA,
IA, and GPS devices.
