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.
The P2040A uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all digital method.
The P2040A 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 P2040A is targeted towards digital flat panel
applications for notebook PCs, palm-size PCs, office
automation equipments and LCD monitors.
