ASM3P5821A Datasheet Low Power Emi Reduction Ic

Manufacturer: Alliance Semiconductor Corporation

Overview: October 2003 .. ASM3P5821A rev 1.0.

General Description

The ASM3P5821A is a versatile spread spectrum frequency modulator designed specifically for input clock frequencies in the range of 20MHz – 34MHz.

The ASM3P5821A can generate an EMI reduced clock from crystal, ceramic resonator, or system clock.

The ASM3P5821A offers a percentage deviation of –1.5%.
