Spread Spectrum Clock
Generator for Mobile
Applications
Description
The ASM3P2187A/B is a versatile spread spectrum frequency
modulator designed specifically for a wide range of clock frequencies.
The ASM3P2187A/B reduces electromagnetic interference (EMI) at
the clock source, allowing system wide reduction of EMI of all clock
dependent signals. The ASM3P2187A/B 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.
ASM3P2187A device has an option of Spread ON/OFF and
ASM3P2187B device has Powerdown option.
Application
The ASM3P2187A/B is targeted towards mobile phones, mobile
audio players and PDAs.
