Product Description
The P2040A is a versatile spread spectrum frequency modulator designed specifically for digital flat panel applications. The P2040A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P2040A 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.

◾ FCC approved method of EMI attenuation.
◾ Provides up to 20dB of EMI suppression.
◾ Generates a low EMI spread spectrum clock of the input frequency.
◾ Input frequency range: 30MHz to 100MHz.
◾ Optimized for VGA, SVGA, and higher resolution XGA LCD Panels.
◾ Internal loop filter minimizes external components and board space.
◾ Six selectable high spread ranges up to ± 2%.
◾ Two selectable modulation rates.
◾ SSON# control pin for spread spectrum enable and disable options.
◾ Low cycle-to-cycle jitter.
◾ Wide operating range.
◾ Low power CMOS design.
◾ Supports most mobile graphic accelerator specifications.
◾ Products available for automotive temperature range. (Refer Spread Spectrum Range Selection Tables)
◾ Available in 8-pin SOIC and TSSOP Packages.

    The P2040A is targeted towards digital flat panel applications for notebook PCs, palm-size PCs, office automation equipments and LCD monitors.
