ASM3P18S19B Overview
The ASM3P18S19B is a Versatile Spread Spectrum Frequency Modulator designed specifically for input clock frequencies from 20 to 40MHz. (Refer Input Frequency and Modulation Rate Table). The ASM3P18S19B reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals.
