P1727 - Notebook LCD Panel EMI Reduction IC

Datasheet Summary

Description

The P1727 is a versatile spread spectrum frequency modulator designed specifically for a wide range of clock frequencies.

The P1727 reduces electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream (clock and data dependent signals).

Features

  • FCC approved method of EMI attenuation.
  • Generates a low EMI spread spectrum of the input clock frequency.
  • Optimized for frequency range: P1727X: 20MHz to 40MHz.
  • Internal loop filter minimizes external components and board space.
  • 8 different frequency deviations ranging from ±0.625% to.
  • 3.50%.
  • Low inherent Cycle-to-cycle jitter.
  • 3.3V Operating Voltage.
  • Supports notebook VGA and other LCD timing controller.
