Product Description
The P2040C is a selectable spread spectrum frequency
modulator designed specifically for digital flat panel
applications. The P2040C reduces electromagnetic
interference (EMI) at the clock source which provides

system wide reduction of EMI of all clock dependent
signals. The P2040C allows significant system cost
savings by reducing the number of circuit board layers and
shielding that are traditionally required to pass EMI
regulations.
The P2040C uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all-digital method. The
P2040C 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 result in a 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 P2040C is targeted towards digital flat panel
applications for Notebook PCs, Palm-size PCs, Office
Automation Equipments and LCD Monitors.
