General Description

The P2041 is a selectable spread spectrum frequency modulator designed specifically for PC peripheral and embedded controller markets .The P2041 reduces electromagnetic interference (EMI) at Block Diagram P2041A the clock source which provides system wide reduction of EMI of all clock dependent signals.

The P2041 allows significant system cost savings by reducing the number of circuit board layers and shielding that are traditionally required to pass EMI regulations.

The P2041 uses the most efficient and optimized modulation profile approved by the FCC and is implemented in a proprietary all-digital method.

Key Features

  • FCC approved method of EMI attenuation.
  • Provides up to 20 dB of EMI suppression.
  • Generates a low EMI spread spectrum clock of the input frequency.
  • Optimized for 25 MHz to 60MHz input frequency range.
  • Internal loop filter minimizes external components and board space.
  • 4 selectable spread ranges.
  • SSON control pin for spread spectrum enable and disable options.
  • Characterizes to work with EMI-Lator®, EMC simulation program.
  • Low cycle-to-cycle jitter.
