Product Description
The P2042A is a versatile spread spectrum frequency
modulator designed specifically for digital flat panel
applications.
The
P2042A
reduces
electromagnetic
interference (EMI) at the clock source, allowing system
wide reduction of EMI of down stream clock and data
dependent signals. The P2042A 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 P2042A uses the most efficient and optimized
modulation
profile
approved
by
the
FCC
and
is
implemented in a proprietary all digital method.
The P2042A 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
P2042A is
targeted
towards
digital flat panel
applications for notebook PCs, palm-size PCs, office
automation equipments and LCD monitors.
