The ASM3P2853A is a versatile spread spectrum frequency modulator. The ASM3P2853A reduces electromagnetic interference (EMI) at the clock source. The ASM3P2853A allows significant system cost savings by reducing the number of circuit board layers and Block Diagram VDD PWDNB XIN XOUT Crystal Oscillator PLL1 USB Clock (48 MHz Unmodulated) 50 MHz Modulated.
Generates an EMI optimized clock signal at output. Input frequency: 25 MHz. Frequency outputs: o o USB Clock (48 MHz unmodulated) 50 MHz (modulated), ±1% centre spread shielding that are required to pass EMI regulations. The ASM3P2853A 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. Lowering EMI by increasing a signal’s bandwidth is called spread spectrum clock .
