P1817B - Low-Power Mobile VGA EMI Reduction IC

Download the P1817B datasheet PDF. This datasheet also covers the P1817A variant, as both devices belong to the same low-power mobile vga emi reduction ic family and are provided as variant models within a single manufacturer datasheet.

General Description

The P1817 is a versatile spread spectrum frequency modulator designed specifically for input clock frequencies.

Key Features

  • FCC approved method of EMI attenuation. Generates a low EMI spread spectrum clock of the input frequency. Optimized for frequency range from: o o P1817A.
  • 20 to 30MHz. Operation P1817B.
  • 10 to 20MHz Operation P1817A/B down stream clock and data dependent signals. The P1817 allows significant system cost savings by reducing the number of circuit board layers ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations. The P1817 m.

www.DataSheet4U.com October 2003 rev 1.0 Low-Power Mobile VGA EMI Reduction IC Features FCC approved method of EMI attenuation. Generates a low EMI spread spectrum clock of the input frequency. Optimized for frequency range from: o o P1817A – 20 to 30MHz. Operation P1817B – 10 to 20MHz Operation P1817A/B down stream clock and data dependent signals. The P1817 allows significant system cost savings by reducing the number of circuit board layers ferrite beads, shielding and other passive components that are traditionally required to pass EMI regulations. The P1817 modulates the output of a single PLL in order to “spread” the bandwidth of a synthesized clock, and more importantly, decreases the peak amplitudes of its harmonics.
