Product Description The P2180/81X is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies from 20MHz to 40MHz and 60MHz to 160MHz (Refer Input Frequency and Modulation Rate Table.) The P2180/81X can generate an EMI reduced clock form an OSC or a system generated clock. The P2180/81A to P2180/81D offer various combinations of spread options and percentage deviations. (Refer Spread Deviation Selections Table.) These combinations include Down and Center Spread and percentage deviation range from ± 0.625% to –3.50%. The P2180/81X reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals. The P2180/81X allows significant system cost savings by reducing the number of circuit board layers and shielding that are traditionally required to pass EMI regulations. The P2180/81X modulates the output of a single PLL in order to “spread” the bandwidth of a synthesized clock, thereby decreasing 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 clock generators. Lowering EMI by increasing a signal’s bandwidth is called spread spectrum clock generation. The P2180/81X uses the most efficient and optimized modulation profile approved by the FCC and is implemented by using a proprietary all-digital method. Applications The P2180/81X is targeted towards EMI management for memory and LVDS interfaces in mobile graphic chipsets and high-speed digital applications such as PC peripheral devices, consumer electronics, and embedded controller systems. |
