external
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” reducing the number of
circuit board layers and shielding that are traditionally
required to pass EMI regulations.
The P2160 uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all-digital method.
The P2160 modulates the output of a single PLL in
order to “spread” the bandwidth of a synthesized
clock and, more importantly, decreases the peak
amplitudes
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 P2160 is targeted towards digital flat panel
applications for Notebook PCs, Palm-size PCs, Office
Automation Equipments, and LCD Monitors, Digital
Still Cameras and GPS Devices.
