General 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.

The P28XX can generate an EMI reduced clock from crystal, ceramic resonator, or system clock.

Overview

P2811A/B and P2812A/B and P2814A/B Low Power EMI Reduction IC.

Key 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.
