| February 2007 rev 1.3 Notebook LCD Panel EMI Reduction IC Features * * * * * * * * P1707A the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P1707A 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. The P1707A 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'. The P1707A uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all digital method. FCC approved method of EMI attenuation. Generates a low EMI spread spectrum clock of the input frequency. Optimized for frequency range from 60MHz to 175MHz. Internal loop filter minimizes external components and board space. Four selectable spread ranges. Low inherent Cycle-to-cycle jitter. 3.3V Operating Voltage. Ultra-low power CMOS design. * * * 14.85 mA @3.3V, 140MHz 16.69 mA @3.3V, 162MHz 17.78 mA @3.3V, 175MHz * * * * Supports notebook VGA and other LCD timing controller applications. Pinout compatible to ICS MK1707 and Cypress CY25561/CY25560. SSON/SBM pin for Spread Spectrum On/Off and Standby Mode controls. Available in 8-pin SOIC and TSSOP Packages. Applications The P1707A is targeted towards notebook LCD displays, and other displays using an LVDS interface, PC peripheral devices, and embedded systems.
