ASM3P2508A Datasheet (Alliance Semiconductor Corporation)

ASM3P2508A, Peak EMI Reducing Solution

The ASM3P2508A is a versatile spread spectrum frequency modulator.

The ASM3P2508A reduces electromagnetic interference (EMI) at the clock source.

location selects a 48 MHz clock output.

However, the I2C block, crystal oscillator, and the PLL block generating 120MHz would be always running.
