PCS3P2537A - Peak EMI Reduction IC

General Description

PCS3P2537A is a 1x spread spectrum frequency modulator designed to reduce electromagnetic interference (EMI) at the clock source, allowing system wide reduction of EMI of down stream clock and data dependent signals.

Key Features

  • 1x Peak EMI Reduction IC.
  • Input Frequency: 18MHz-36MHz.
  • Output Frequency: 18MHz-36MHz.
  • Frequency Deviation @ 27MHz: -0.25%.
  • Modulation Rate @ 27MHz: 30.1KHz.
  • Supply Voltage: 3.3V ± 0.3V.
  • Operating current less than 8mA @ 27MHz.
  • Spread Spectrum Enable Control.
  • CMOS design.
  • 8L-WDFN (8L-TDFN) package PCS3P2537A modulates the output of www. DataSheet4U. com a single PLL in order to “spread” the bandwidth of a sy.

This result in significantly lower system EMI compared to the typical narrow band signal produced by oscillators and most frequency generators. Lowering EMI by increasing a signal’s bandwidth is called ‘spread spectrum clock generation.
