P2779A - Low-Cost Notebook EMI Reduction

Datasheet Summary

Description

The P2779A is a versatile spread spectrum frequency modulator designed specifically for mobile and digital camera and other digital video and imaging applications.

Features

  • Provides up to 15 dB of EMI suppression FCC approved method of EMI attenuation Generates a 1X low EMI spread spectrum clock of the input frequency Operates between 20MHz and 38MHz input frequency range External loop filter for spread percentage adjustment Spreading ranges from ±0.25% to ±2.5%.
  • Ultra low cycle-to-cycle jitter Zero-cycle slip at small deviation.
