Overview
ASM3P2187A, ASM3P2187B Product Preview 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.
