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.
