Datasheet Summary

Description

The P28XX devices are versatile spread spectrum frequency modulators designed specifically for a wide range of input clock frequencies from 10MHz to 40MHz.

Refer to Input/output Frequency Range Selection Table.

Features

  • FCC approved method of EMI attenuation.
  • Provides up to 15dB EMI reduction.
  • Generates a 1x, 2x and 4x low EMI spread spectrum clock of the input frequency o 1x: P2811A/B o 2x: P2812A/B o 4x: P2814A/B.
  • Optimized for input frequency range from 10MHz to 40MHz.
  • Internal loop filter minimizes external components and board space.
  • Selectable spread options: o Down Spread and Center Spread.
  • 8 frequency deviation selections: o ±0.625% to -3.5.
