ASM3P2474A Datasheet Low Power Peak Emi Reducing Solution

Manufacturer: Alliance Semiconductor Corporation

Overview: October 2005 .. rev 1.0 ASM3P2474A Low Power Peak EMI Reducing.

General Description

The ASM3P2474A is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies.

The ASM3P2474A reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of all clock dependent signals.

The ASM3P2474A allows significant system cost savings by reducing the number of circuit board layers, ferrite beads and shielding that are traditionally required to pass EMI regulations.

Key Features

  • Generates an EMI optimized clock signal at the output. Integrated loop filter components. Operates with a 3.3V Supply. Operating current less than 6mA. Low power CMOS design. Input frequency range : 13MHz to 30MHz Generates a 1X and 2X low EMI spread spectrum clock of the input frequency. Output Frequency Selection through FSEL pin Frequency deviation : -1.5% (Typ) @25MHz : -1.5% (Typ) @50MHz Available in 6-pin TSOT-23, 8-pin SOIC and 8-pin T.
