onsemi P2008A
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.| Part No. | P2008A |

DESCRIPTION
The P2008A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method. The P2008A 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 P2008A is targeted towards cable, xDSL, fax modem, set−top box, USB controller, DSC, and other embedded systems.FEATURES
