Product Description
The P2008A is a versatile spread spectrum frequency modulator designed specifically for digital camera and other digital video and imaging applications. The P2008A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P2008A 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.
FEATUREs
◾ FCC approved method of EMI attenuation.
◾ Provides up to 15dB of EMI suppression.
◾ Generates a 1X or ½ X low EMI spread spectrum
clock of the input frequency.
◾ Input frequency range: 4MHz to 32MHz.
◾ Internal loop filter minimizes external components
and board space.
◾ Spreading ranges from ±0.8% to ±3.2%.
◾ SSON# control pin for spread spectrum enable
and disable options.
◾ Low Cycle-to-Cycle jitter.
◾ 3.3V Operating Voltage.
◾ Ultra-low power CMOS design.
◾ Available in 8-pin SOIC and TSSOP Packages.
APPLICATIONs
The P2008A is targeted towards cable, xDSL, fax modem, set-top box, USB controller, DSC, and other embedded systems.
