Product Description
The P2681A is a versatile spread spectrum
frequency modulator designed specifically for digital
camera and other digital video and imaging
applications. The P2681A reduces electromagnetic
interference (EMI) at the clock source, which
provides system wide reduction of EMI of all clock
dependent signals. The P2681A allows significant

system cost savings by reducing the number of circuit
board layers and shielding that are traditionally
required to pass EMI regulations.
The P2681A uses the most efficient and optimized
modulation profile approved by the FCC.
The P2681A modulates the output of a single PLL in
order to 鈥渟pread鈥?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鈥檚 bandwidth is called 鈥渟pread
spectrum clock generation鈥?
Applications
The P2681A is targeted towards MFP, xDSL, fax
modem, set-top box, USB controller, DSC, and
embedded systems.
