Product Description
The P2010A is a selectable spread spectrum frequency
modulator designed specifically for PC peripheral and
embedded controller markets. The P2010A reduces
electromagnetic interference (EMI) at the clock source
which provides system wide reduction of EMI of all clock
dependent signals. The P2010A allows significant system
cost savings by reducing the number of circuit board layers
and shielding that are traditionally required to pass EMI
regulations.
The P2010A uses the most efficient and optimized
modulation profile approved by the FCC and is
implemented in a proprietary all-digital method.
The P2010A 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 P2010A is targeted towards the embedded controller
market and PC peripheral markets including scanners,
facsimile, MFP’s, printers, PDA, IA, and GPS devices
.
