ASM3P2870A - Low Power Peak EMI Reducing Solution

Description

The ASM3P2870A is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies.

The ASM3P2870A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals.

Features

  • Generates an EMI optimized clock signal at the output. Integrated loop filter components. Operates with a 3.3 / 2.5V Supply. Operating current less than 4mA. Low power CMOS design. Input frequency range: 13MHz to 30MHz for 2.5V. : 13MHz to 30MHz for 3.3V. Generates a 1X low EMI spread spectrum clock of the input frequency. Frequency deviation: ±0.75% ( Typ ) @ 22MHz Input Frequency. Available in 6-pin TSOT-23, 8-pin SOIC and 8-pin TSSOP Packages.
