Product Description
The P18xx is a versatile spread spectrum frequency modulator designed specifically for a wide range of input clock frequencies from 10 to 160 MHz (see Input Frequency and Modulation Rate Selections). The P18xx can generate an EMI reduced clock from crystal, ceramic resonator, or system clock. The P18xx-A to P18xx-H offer various combinations of spread options and percentage deviations (see Spread Deviation Selections). These combinations include Down Spread, Center Spread and percentage deviation range from ±0.625 to -3.50.
