ASM3P2111A - Peak EMI Reducing Solution

General Description

The ASM3P2111A is a versatile spread spectrum frequency modulator.

The ASM3P2111A reduces electromagnetic interference (EMI) at the clock source.

Key Features

  • Generates an EMI optimized clocking signal at output. Input frequency.
  • 25 MHz. Frequency outputs: o o o.
  • 60 MHz (unmodulated) 2 x 48 MHz (unmodulated) 66.6 MHz (modulated) -1.7% down spread The ASM3P2111A allows significant system cost savings by reducing the number of circuit board layers and shielding that are required to pass EMI regulations. The ASM3P2111A modulates the output of PLL in order to spread the bandwidth of a synthesized clock, t.

Frequency outputs: o o o ƒ ƒ ƒ ƒ 60 MHz (unmodulated) 2 x 48 MHz (unmodulated) 66.6 MHz (modulated) -1.7% down spread The ASM3P2111A allows significant system cost savings by reducing the number of circuit board layers and shielding that are required to pass EMI regulations. The ASM3P2111A modulates the output of PLL in order to spread the bandwidth of a synthesized clock, thereby decreasing the peak amplitudes of its harmonics. This results in significantly lower system EMI compared to the typical narrow band signal produced by oscillators and most clock generators.
