Alliance Semiconductor ASM3P2108A Spread Spectrum Frequency Modulator Datasheet
The ASM3P2108A is a versatile spread spectrum frequency modulator designed specifically for input clock frequencies ranging from 25MHz to 45MHz. It generates an EMI-reduced clock from crystal, ceramic resonator, or system clock sources. The device uses a proprietary all-digital method to modulate the output of a single PLL, effectively decreasing the peak amplitudes of harmonics and lowering system-wide electromagnetic interference (EMI).
