Product Description
The P2041 is a selectable spread spectrum
frequency modulator designed specifically for PC
peripheral and embedded controller markets .The
P2041 reduces electromagnetic interference (EMI) at
Block Diagram
P2041A
the clock source which provides system wide
reduction of EMI of all clock dependent signals. The
P2041 allows significant system cost savings by
reducing the number of circuit board layers and
shielding that are traditionally required to pass EMI
regulations.
The P2041 uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all-digital method.
The P2041 modulates the output of a single PLL in
order to 鈥渟pread鈥?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鈥檚 bandwidth is called 鈥渟pread
spectrum clock generation鈥?
Applications
The P2041 is targeted towards the embedded
controller market and PC peripheral markets
including scanners, MFP鈥檚, printers, PDA, IA , and
GPS devices.
