P1821 Product details

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).

Features

FCC approved method of EMI attenuation Provides up to 15 dB EMI reduction Generates a low EMI spread spectrum clock and a non-spread reference clock of the input frequency Optimized for frequency range from 10 MHz to 160 MHz P1818: 10 to 20 MHz P1819: 20 to 40 MHz P1820: 40 to 80 MHz P1821: 10 to 40 MHz P1822: 80 to 160 MHz Internal loop filter minimizes external components and board space.
